HTC Prophet

http://x.msmobiles.com/portal/images/htc/htc-prophet.jpg
I was reading this on MS Mobiles looks interesting
We have got this photo and information from our sources at O2 and here are some further highlights about HTC Prophet that are known by now:
built-in FM Radio
built-in Wi-Fi (unknown whether also 802.11g or only 802.11b)
powered by Windows Mobile 5.0
processor: 416 MHz
display: QVGA (240x320 pixels), 65k colors
camera: 2 megapixel with Flash
form factor: Similar size as Magician but Slimmer.
cellular networks support: EDGE, GPRS, GSM
ROM and RAM: still no information available
Please note, that O2 Xda Atom, that O2 Asia will start selling in December 2005 is not made by HTC but by Quanta - although having very similar specifications like HTC Prophet.
Conclusion: built-in FM Radio is extremely important in some countries, particularly in Asia, and therefore having a HTC made Pocket PC phone with built-in FM radio will be crucial for overall success of Windows Mobile phones. [/quote]

FM Radio would be nice, but that thing's ugly :/

FM BAND 108 Mhz to 133 Mhz ???

Hi,
Is it possible to change FM band to receive 108 Mhz to 133 Mhz ? ( Change the Diamond FM Radio' s wave band/scan range/spectrum ?)
HTC TOUCH DIAMOND
ROM : 1.93.401.2 WWE
Radio : 1.00.25.07

Why would you like to do that?
>FM radio frequencies are Airborne frequencies and they are amplitude modulated i.e AM.

You are right. I'd like to listen Airborn frequencies. Is it possible with Diamond ?

Id actually like to know if it is possible as well, alot of cool frequincies in that range, airtraffic, police, firestation... would be cool to be able to use the diamond as a frequency scanner as well

AM or SSB or PM are different moduleation forms then fm
am is amplitude modulated
ssb is single side band == only info in ½ the am "sinus"
pm is pherse modulated
fm is frequency modulated
they cant recieve signals from other modulations
and unless a fm radio was made to recieve from other ranges
it's impossible to change it
with old type of radios one can change the components
called crystals to match other hz's but if it's inside a chip it's not possible

Ok , but airtraffic comunications are FM (108 to 133 mhz). Is it possible to set Diamond to FM Band 108 mhz / 133 mhz ??? I know ... it is possible to change a normal FM receiver to listen 108 Mhz to 133 Mhz instead 88 mhz to 108 Mhz ...
Do you know if it is possible ???? Thanks.

i cant say but i doubt it

Radio Frequency change
Actually, the radios in most current PDA / Cellphones are run by software -hence, for example the RADIO software in the boot rom being different based on the version number - causing different battery drains, lock-on time for GPS, etc.
What is needed is a set of spec sheets for the hardware inside the phone and then an "expert software" package to disassemble and label the code within the Radio software. These can sometimes be provided by the hardware manufacturer - not the phone/PDA manufacturer - but Intel, Motorola or other such.
After that, if the timers and registers can be reset to different frequencies (it is all done by 'countdown' timers and dividers) then yes, the radio CAN be changed to cover different frequencies - such as Aircraft bands.
And, yes, I know this because I have designed microcode for such devices before - but I got out of the business because it has become too, too demanding on an older gentleman such as myself.

yes i made a ssb radio in a dsp once as a project but even if it's software
it dont change what range of Hz's one can recieve
the first filters in the line before the dsp get to "play" with the signal
set the limit of what range is possible
that being said i dont know for suden what the max range the chip in
the diamond
but few companys who want to make money spend alot of money on hardware
which is able to give more then they need in terms of range and the likes

In digital radios, even the inline filters are digital, and most (like cellphones) have a large set of dividers and multipliers in the head end, the base frequency on many of the phones is 2.3 GHz and then that is frequency multiplied or divided to get to a harmonic of the frequency wanted, and after applying digital bandpass, hipass and lopass filters to chomp out the "grass" they end up with the frequencies wanted. Most all of that is done inside a single chip these days - they don't use DSPs much anymore - they have complete head end, intermediate, FM/AM/FSK/SB and DV outputs right from the single chip now. (I really did do this carp for a living, guys.... )
Dont forget that MOST ot the PDA/Cellphone users are blind to even the idea that the thing is completely built with software - they just "take it as it is". If you think about the MILLIONS of users out there with HTC products in thier hands and how FEW are really in this forum, it doesnt take much to see that the companies are pretty safe about making money - not to mention that they bring out new bells and gadgets every 12 to 18 months too, just to keep the money rolling in!

to be able to sample a signal one is required to according to nyquist
to use at least 2 times the hz as the signal you are sampling
with the dsp i used ADSP 8150 EZ-Kit Light board
i had a 300Mhz dsp and samping Mhz or even 1XXKhz signal would
be imposible without a pre downsampling system analog or asic

Yuppers.... an ASIC is only one segment of the headend inside the primary radio chip. Current ASIC's can take a 2.3GHz input and create a reference from 40MHz up to 18GHz with a max of 8dbm insertion loss to the secondary segments. From there, you can probably guess what can be done - since the reference is 40MHz to 20GHz, then changing the operating radio band and the bandwidth is just a matter of changing the preload values in 10 or 12 downcounter registers, setting the ouptut format and channeling the analog to the proper device(s) -
I was a subroutine programmer for some military development work which used a Freescale MXC300-30 (modified for the particular use) and I tell you, the things that chip could do..... holybejeezus!!!!
The master clock was 600MHz but it could handle WDCMA Tri-band to 1900 MHz [1.9GHz] while handling the audio and video conversions (much slower clock rates - 128 KHz and 1.75 MHz) and do this all at the same time as it was providing the master processor clock and a few other things as well.
Ah well... those days are over (thank God!)

Any DevGods working on Windows Phone 7 Series??

I want it badly on my X1!!!!!!!

it is not even release yet. READ BE4 ask.

Chances are it'll make your X1 really slow

Your X1 will explode if you attempt to put WP7 in it.
WP7 is not written for the X1 hardware.

X1 is slow with the WM6.5 and you want WM7???
If we are not sure tha HD2 gets WM7 update, imagine about the X1.... No chance, at all!!

Well, in the first place, if these are the minimum required specs, even X2 (not to say X1) can't run Windows 7.
- Large WVGA screen with a single aspect ratio (which means BlackBerry-style devices won't be readily available to begin with)
- Five specific hardware buttons required: Start, back, search (a dedicated Bing button), camera button, and power -- no more, no less
- Capacitive multitouch
- CPU and GPU requirements (beginning with Qualcomm's Snapdragon as the go-to processor)
- WiFi
- AGPS
- Accelerometer
- FM radio
- High resolution camera

I have also been hearing that there isn't a MSM7200 BSP for WM7, only QSD, so it's likely that we won't be able to get anything working at all.

In the past 3 months I've seen 8 different versions of the WM7 system requirements. Is that the real, honest-to-goodness, final one?

all these versions include some hw-specs the x1 simply doesn't have. (acc-meter for example)
but doesn't matter. all the drivers are closed-source (wifi, keyb, graphics, screen etc etc), they're directly available only to OEMs. ever noticed the problems on android-development? so unless SE delivers a firmware-version built for WP7, it will always just be reverse-engineering resulting in bad performance. (wait a sec, SE updating the x1? i think there was an official statement concerning that? )
to the thread-starter:
there's a german saying, "there are no dumb questions, only dumb answers." well sorry, but in your case the question is very dumb. WP7 hasn't been delievered to the manufactures yet, it's a work in progress inside MS. think again?!
edit:
just remembered the update-schedule for the x2, where it's clearly stated at the the end:
"(ps. Before anyone asks, no it won’t ever go onto Windows Mobile 7, it won’t support the hardware.)"
so, if the x2 can't run it, neither can the x1.

There's also the Windows Phone Starter Edition..?
Maybe that's 'lite' enough for X1's hardware.

After reading about it, I don't even want WP7 OS. I want the hardware, so my phone is like a rocket, but I don't get the excitement over "hubs." Guess it's because I'm not into games and Facebook.

isn't that windows phone 6 starter edition? also from what's been said about it, it will be a downgraded version, not capable of hdspa and without office, for example.
and even IF there is a starter edition of winpho 7 - the driver problem persists.

i know of lite versions..atleast in comps, they are no-frills..so lets hope and pray we have one no-frills WinMo7 for X1 also.....

Lumia 820 jail broken

Lumia 820 jailbroken, it worked but it was not so smoothly and doesn't even good for jail broken. I tried my lumia 820 jail broken damn delay
Need have a good processor and good ram only jail break will get a good result

Um... assuming you mean Developer Unlock then yes it is actually possible. My Lumia 920 is dev unlocked (or as you call "Jailbroken"). I cannot seem to understand the second part, are you claiming that your device became slower after the dev unlock and you want to upgrade your processor and RAM?

UM... Seriously updated to JAILBROKEN will be delay, so I updated my window phone with RAM, Processor can't be update
So you can try many fun in window phone, it many fun in window phone like computer :0

I don't know what your native language is, but could you please type your post in that and then use an online translator to English? I can't understand what you're trying to say at all. You can't upgrade the RAM in a Windows Phone (or any other phone that I know of) unless you just mean switching models. It has nothing to do with dev-unlock or any other "jailbreak" sort of feature anyhow. There's no "jailbreak" for Windows Phone 8 right now, although there is an official Developer Unlock feature which allows a limited number of low-permission sideloaded apps. Despite the name, Windows Phone is not much like Windows; there's no Desktop mode, you can't access the file system or registry except through the extremely low-privilege (sandboxed) apps and the indirect control of the Settings (Control Panel, basically) section. You certainly can't run Windows (Client, as in, desktop/laptop PC) software on Windows Phone, even with developer unlock.

Slow file transfer to phone with all methods (adb/MTP/FTP-usb-modem/FTP-802.11ac)

Hi, I experience something that I consider a very strange problem.
I recently bought a Mi 9 and discovered that its USB-typeC is only USB 2.0. This is rather disappointing, but USB 2.0 should still give 480 mbit/s = 60 MB/s transfer speed.
However, the real USB file transfer speed from PC to the phone is only 27 MB/s.
I've tried everything - MTP/PTP, adb, running FTP server on the phone through "usb modem" network.
I even setup Linux hostapd on my laptop which has 802.11ac with an Atheros chip, connected the phone to that network and got 780 mbit/s theoretical speed.
Then I started an FTP server and retested: still 27 (maybe 28-29) MB/s to the phone. At the same time, it reached the speed of 65 MB/s (=520 mbit/s) when copying a file FROM the phone to the PC.
Then I even launched Terminal emulator and started a download from the PC to the phone with `curl`. And guess what, I still got 27-30 MB/s. Even when it's downloading the file to /dev/null instead of the phone's flash memory - it still gives 27-30 MB/s.
Then I launched THREE curl's at the same time. Three of them gave me 30+30+20 MB/s = 80 MB/s = 640 mbit/s which means that my 802.11ac worked correctly.
So my question is: what is that fixed limit of 30 MB/s per process?
And what file transfer speeds do you get with your Mi9's?

im not so technical with specs of write/read speeds but, at least i can say the same, mine to transfer around 6GB takes about 30 to 40 minuts so, i guess is around 25 to 30 mb/s, USB 2.0 on a phone this good is the only downside to have a phone without microSD slot to compensate the slow USB 2.0 speed, or worse than that.

It's worse. 6000MB/(30*60) = 3 MB/s...
With 27MB/s it should take ~4 minutes to copy a 6 GB file...
And it should be even more, most usb 2.0 sata enclosures max out at 50-60 MB/s...

and i am talking about 6GB of more than 1300 pictures with ~3 to 5mb each so, probably will take more cause is not a single file.
i dont know wich method you use but i connect my phone and select MTP not PTP.
evenm its so damn slow, i regret the speed i can go with my G6 wich have usb 3.1 and thats was amazing quickly compared to Mi9.
i dont know why Xiaomi dont implement usb 3.1 on their high end models, they can make it, and even if we need to pay 10 to 20 bucks more is way way better than waste a lot of time copying files into it. - since they didnt provide microSD eighter.

My redmi note 9 also slow transfer speed but it solved now, on PC I compress all the files, transfer compressed file to the phone the extract it on the phone.

That is the THEORETICAL MAXIMUM that USB 2.0 can achieve. In practice, NO USB 2.0 drives, I repeat, NO USB 2.0 drives ever reach that speed. The fastest one reaches only 42MBps sequential write speed and is an externally powered hard drive, while the fastest flash drive only reaches 25MBps sequential write speed (data taken from usb.userbenchmark.com, so it's sourced from multiple real world users instead of a controlled lab environment). Your 27MBps then is already a good one.
