Still trying to find a method to root the device, then WM is pretty much further (and uninteresting sincerely). Buying a Tattoo for WM is a really bad idea, I don't even know if the processor can support WM
Windows Mobile is closed source, so no, it possibly couldn't be done.
Windows Mobile is lame anyway, it's actually a dummified version of Windows 2000 running some pretty GUI. Win Mobile is also a GUI on top of Windows CE, I believe the latest version is WinCE 6.5.
WinCE afaik needs to be compiled for specific CPU and such... It's not a one-size-fits-all setup. Sorry to pop your bubble.

Theres no doubt Windows can do more than Android can in certain areas that really make a device useful. Windows Mobile= Mini PC w/phone capabilities, and Android= Modern Smart phone/w PC like functionality. It's all up to what you want in a phone..but if you gave me a Mini PC Phone..all in one word..that will be winner.
Cant understand WHY anyone wants WM ??? Its **** compare to Android in my world
OK, Could be nice with update for android to 2.x but windows mobile = hell no....
WM Shouldn't be a priority - Let's root and update
I have owned several WM devices, and Android is way superior than WM. Why would you buy a tattoo and then convert it? You should have bought a WM device if you want WM. Anyway, we should first be able to root the device, and update to 2.1.
Let us get our priorities right people!
besides being free source and visually more appealing i fail to see where exactly does android out do windows mobile???? Functionality ways according to me nothing beats windows mobile. I upgraded to the hero just to try something different, just to see what android is like..and in no way is it better than windows mobile....if ur talking about sense ui, facebook integration, and all the million other widgets that make your experience a great one.....that isn't the android OS per se...theyre just add ons. any way SPB mobile 3.5 is still better than the sense ui that we get on our phones.
things i didn't like about android:
-No bluetooth file transfer(at least in the version im running on the hero now)
-No bluetooth tethering option(i used to use this a lot on my windows phone)
-no option of installing programs on sd card( i had to root and install apps to sd, that too cache still remains on the phone memory)
-lacks basic programs when it comes from the factory, being a smart phone one would expect it to ship with basic programs like a file explorer and an office suite. but no...this phone overly depends on the market for everything.
conclusion
Although android is developing fast and seems to have a promising future, it is yet to become as good as windows mobile let alone out doing it. if i had the money i would surely buy an HD2.
We all know Android looks nicer but how does that make it superior? Wouldn't the operation system with the most features be ahead? Windows mobile will get flash 10.1 support first..windows CE usually powers all the intese 3D U.I's you see in embedded devices. Even nvidia has said they prefer the windows kernel over linux for doing 3D applications. I'm just saying the next windows mobile is obviously going be like holding a Mini Gaming PC from 2005-2006 in your pocket. Android will have to impress me with just good looks, and open source goodness..if theres an alternative that can actually do more. Dont get me wrong though, once i've booted Android on my device I never looked backed at windows again.
Whoopeedoo, a smartphone with a 3D UI. Big deal. Windows Mobile is horrible on Battery Life, I had a Windows Mobile PDA and it was in standby after a full charge, and it just drained like crazy yet it was idle.
Android is open source. It can be extended, edited and used for any task - It powers some eBook readers. Windows Mobile is crap, it's based on Windows NT Kernel (yes, that's correct) and you can't develop apps for WM unless you learn all the .NET garbage.
FACT: Android supports Bluetooth File Transfer via custom APK.
Go get a HTC Hero or HTC Dream with Quickoffice if you want some office app on your phone. Who would want to type a school assignment on their phone anyway?
I'll be a linux and android supporter, I'm not going to be corrupted with Windows Mobile. I use Windows CE + Linux on my Jornada HPC, so I'll have a shot at porting Android over to it.
@above
whatever suits you dude. For me, yes i can live with android(till i can afford the HD2) but the experience is not as pleasing as it was on the win mobile platform. As far as battery life goes, i have never had any issue with win mob, its pretty much the same as android...... well at least for my usage.
NO the android 1.5 that i currently run on the HERO does not support bluetooth file transfer or tethering even via a custom apk, although the much acclaimed 2.0 and newer versions do. But sadly there hasn't yet been any official release from HTC and the leaked roms though good (thanks to the efforts of the devs) aren't stable enough for my daily usage. In the end it all boils down to personal preference and your needs, whats superior and whats not doesn't matter really.

Yeah, I'm just saying the next high end windows phones will bring mobile smartphones into the next level. It will support higher res 1200x600 screens ,multiple screen support, being able to output movies, and UI to your TV..making it a true portable media device. You'll basically have a xbox 360/Zune/PC in your pocket.
hers what to do
send me your tatoo
ill send you my htc touch mk 1
fair swap
you get windows
i get anotheR lovely android device !!
(( no but seriously the apps you want i can sort of agree with, file managers on android are a whole new thing when your used to win-mob, maybe try linda file manager or astro its just a getting used to process... or we can swap ! ))

Noted, I guess I misread your post as "OMG Android ****, WM pwns". Sorry if I offended you.
I'm sure if people wanted to, they could make a Win Mobile UI for android... but in my opinion, Android has a better feature set and can be hacked more than Windows Mobile can.
Hey i wasn't offended. Any way i agree the win mob UI is ****ty, its just the way the platform works that makes me like it, its very much like the windows pc that we use and are so overly familiar with. May be i will eventually get used to android.
As far as hacking goes....well no one has been able to root the tattoo or the droid eris yet...but almost all win mob devices at least have a soft spl out there.
Again a phone is meant to satisfy an almost unique set of needs of each individual, so yes its all personal preference.
I love the market on the android though..tons of free applications and in future if i had to buy a phone i would always choose a win mob or android phone...had a bad experience with symbian and i simply don't like the i-phone.
True. The iPhone UI is too simple, Windows Mobile had me going around in circles wondering how to send files to another device, and Android is just a "little slice of heaven". Again, that's my two cents, but yes, if any hardcore WM hacker wants a challenge, try porting WM to the HTC Click.
normally such porting is very hard if not impossible as drivers for the tattoo are made to be used with android 1.6, writing drivers from scratch for windows is going to be a royal pain in the @$$ for most developers.
Is there any way to install windows mobile 6.5 on HTC HD7?
WP7 has not many classic windows features and is not realy windows like as we used many years ago. As I read, incoming updates will not contain basic windows components and it is wasting time to waiting updates.
Would be great if is possible to install WM 6.5 on HD7 so it will be realy power Pocket PC.
NO
First post and you ask for wm 6.5 that is has been discused on other thread
try search button and you will find your answer.
Buy an HD2, not an HD7.

What is this answers like NO and BUY some other models. If you haven't answer than you don't posting like this.
If I knew that WP7 is not avdanced continuation (as expected) of WM 6.5 I didn't buy this phone altought has great thechnical specifications.
I read this forums and I saw I'm not alone affected by this problem.
I am familiar with pocket PC and using it many years ago. Now I have not file explorer, bluetooth file transfer, task manager, cannot create folder, download files from internet and save where you want. There are no software tool for digital compass even it is exist in technical specifications.
I just ask for solution without these limitations.

And when did MS say that any of these features were gonna be available in wp7???
yet another person who didn't do his homework, then doesn't understand when he gets flamed for it...
Unfortunately there isn't a solution. IMO i think the features you require will become available via apps before anybody ports wm6.5 over.
How come you didn't research the phone before buying may I ask? It's been well known since long before release throughout the XDA community that WP7 is definately not a continuation of WM6.5, i'm surprised you didn't know.

Office for Windows Phone 8 was the major factor I want to switch from Android to WP8. But there are some rumors and proof also (some screenshots on internet) that say that Microsoft is developing Office 2013 for iOS and Android and will be available for FREE (editing only) on these 2 OS.
It'll have skydrive and everything except editing.
Why Microsoft wants to hamper Windows Phone sales by doing this?
What you think here at Windows Phone 8 forums, how will it affect WP8 sales.
And as a current Android user, should I switch from Android to WP8, now?
If a good office program is the only reason why you want to shift to WP8, have you tried some very good Office Suites for Android.
I suggest to give the following a try :-
1. SoftMaker
2. OfficeSuite Pro 6 by Mobile Systems
Personally I think these (specially Softmaker) are more powerful than the knocked down version of Microsoft Office for WP8
Just a suggestion as I thought this may save you some real hassle of switching platforms.http://forum.xda-developers.com/images/icons/icon12.gif

Firstly this is Windows 8 not windows phone 8.
But in answer to your question. There is no way to update a windows phone 7 device to windows phone 8. Windows phone 8 apps physically cannot run on windows phone 7 as it lacks the APIs to do so. Most developers right now still make apps for windows phone 7 because they can run on both 7 and 8.
If you want windows phone 8 and windows phone 8 apps, get a windows phone 8 handset.
As for upgrading WP7 device to WP8, it's technically not impossible - the hardware can run it (though poorly) - but the WP8 OS was designed to require hardware features not present on WP7 handsets. Consequently, there are no WP7 devices which receive an official update to WP8.

The biggest limitation for an update is a complete kernel swap. WP7 used the windows CE kernel. WP8 uses the windows NT kernel. For all intents and purposes this makes them entirely different operating systems and the technical difficulty of issuing an update for WP7 to 8 would be like releasing an update to the iPhone that installs android or an update to windows 8 which installs OSX.
Its only because WP7 apps are in .NET and it was possible to port .NET to WP8 that WP7 apps do run on WP8. Other than that the only relationships between the 2 platforms are name, general design style and the fact that they are made by the same company.
But otherwise. WP8 could feasibly run on WP7 handsets. Its just it wouldn't be possible to do the same way as regular software updates. Plus most WP7 devices are actually pretty low spec, they were all single core hitting clock speeds of 1.4ghz max, half gb of ram usually. Not beasts of handsets at all.
What do you mean by "regular updates"? Each Windows Phone update required the phone switching to a special "Update OS" boot mode where the "ROM" of the main OS could be modified, and at that point switching out the kernel (and associated userspace libraries) is no harder than, for example, switching out IE7 for IE9 (which the Mango update to WP7 did). Yeah, it's not really the same OS afterward, but so what? The data is still there.
Admittedly, WP7 makes substantial use of Windows Embedded Database and CE Database files, which are accessed through APIs that are CE-specific extensions to the standard Win32 API. Those would either need to be ported to the Win32/NT API, or the data in them would need to be converted to another format during the update... or the phone's configuration would need to be wiped and set up with defaults again, which would kind of suck but still be better than "no WP8 for you; go buy new hardware!"
Anyhow, this whole thread is in the wrong forum. Could somebody do something about that?
I'm about to buy a WP device, and of course it's my first WP device so I was doing some research on it.
We know that Lumia devices to WP are like Nexus device to Android, which means first gets update to new system.
And recently there a lot of wallet-friendly WP phones comes out like Prestigio, Yezz, Blu... etc, and as I have wait for 2 months that Lumia 630 dual sim is still not available in my country so I'm thinking about prestigio multiphone 8500.
Only thing I'm worrying about is system update. I take no doubt it's not gonna be as fast as Lumia devices get.
And I read an article about an app "windows preview for developers", and appears it can run on Lumia, Huawei and Samsung.
So I was wondering how does WP work?
I mean, for example the Android , each device has its own driver so need manufacturer to do the update.
And WP doesn't work that way? just like we saw on PC, one system contains almost all driver?
Each OEM device contains the Windows Phone OS + OEM/Carrier specific firmwares that do include drivers that will add and tweak things for the specific version of WP.
The Preview for Developers program allows a user to update his or her phone to the latest version of the Windows Phone OS ONLY, keeping the current firmware that you had installed BEFORE you updated the OS via the preview for developers. Before updating, Microsoft informs you that if something goes wrong with your phone, that it CAN void your warranty (unless you can get back to a previous version of the OS to match the version that is in production for your carrier).
The carriers will release the OEM/Carrier updates when they are approved.

Hi,
Firstly, although now Nokia's mobile division belongs to Microsoft, I do not think as long as it is a kind of exclusivity for updates. It's just that there are only a duo (or rather all in one) Microsoft/Nokia that move your ass, the rest of the manufacturers do almost nothing, and royally fu** Windows Phone (Huawei, HTC, Samsung, etc). It is therefore felt in the updates:
- Nokia first in almost all the time
- Huawei, HTC, Samsung, etc. last
All this because some OEMs do not want to bet (big) on Windows Phone. This is unfortunate.
In addition, the updates via the Developers Preview for all models of Windows Phone 8 uild OS updates have the same time. Namely, since the GDR3 Preview, the Preview status updates become official once the release for everyone (almost no change the build version between of Preview/official).
On Windows Phone, the packages the OS portion and the firmware part *are separated*, which means that one can go without the other.
Some example (Nokia):
- Preview GDR3 WP8.0 on Lumia Amber (Lumia Amber is fully compatible under GDR2 WP8.0).
- Preview WP8.1 on Lumia Black (Lumia Black is fully compatible under GDR2 WP8.0).
- Preview GDR1 WP8.1 on Lumia Cyan (Lumia Cyan is fully compatible in WP8.1).
- Etc. (along with other OEM).
Of course, for each GDR (at minimum), OEMs need to update their firmware to make it fully compatible at this level (software-hardware).

thanks for your reply.
please forgive my stupidity and poor english, about GDR, can I take it like a big update on Windows , like Service Pack ? at least that's how I felt about this thing ...
what do you mean "Amber", "Black" and "Cyan" ? I assume it's like system name ? like TouchWiz , SenseUI and something ?
so I assume i bought a Prestigio Multiphone 8500 duo (WP8.1) , is it possible i get WP8.1 GDR1 myself ? (even somehow it's problematic and not fully compatible) or I must wait for OEM to do it ?

GDR means "General Distribution Release". GDRs provide bug fixes, modifications of any kind, add features, etc.
If Windows Phone 8 would "equal" (excuse the term) at Windows 7 (not Windows 8, because there are more Service Pack on this version), then yes a GDR would be about equal to a Service Pack.
Lumia Amber, Lumia Black and Lumia Cyan are firmware developed by Nokia. They contain all sorts of things, such as drivers, features, assembly (dll/exe), etc.
Basically, it is the firmware that makes the link between the hardware and the software. All other manufacturers are developing the firmwares for their Windows Phone, only they do not give of name at of their firmware. Nokia does.
All Windows Phone 8 will get the GDR1 of WP8.1, even your device (either by voice Preview, or by the official voice).

if I may , i'd like to know something more about WP.
as we can see in Android , the eco-system is full of fragment , and Google couldn't push OEMs to update their devices, does Microsoft have more control over this matter ?
I mean , how could Microsoft to be so sure about all WP8 devices will get GDR1 ? for Lumia series I can understand , but what about devices of Huawei , Samsung and other OEMs ? how could Microsoft guarantee the update on NO-Lumia devices ?

All Windows Phone 8 device has support in terms of updates. Support for Windows Phone 8 will normally end at the latest in 2016 (for some device).
On this point, you do not have to inquitez, not before long (and in hope that Microsoft to learn from their mistake with WP7).

with all due respect sir , i think you misunderstood me ...
my main question is , how could Microsoft possibly to oversee the update over all other OEMs ? for Lumia , there is no doubts about that ...
like they've made a contract , agreement , or such thing ?
we see how the looser Google is, in the control, special the update part of Android ...:crying:
Microsoft controls the phone update servers. If an OEM doesn't want to release an update for their phone, MS could (in theory) just push the OS update to all users of that phone anyhow. This would be functionally equivalent to using the Preview For Developers option, except doing it for everybody instead of just those who opted into it.
PFD allows you to update any WP8 device from any OEM and on any carrier as though it were an Android Nexus device: you get the updates as soon as Microsoft publishes them, without waiting on OEM/MO customizations and without the OEM or MO having any opportunity to block or delay the update unless it breaks on their firmware (in which case MS will stop pushing the update until it's fixed).
