Dual mode (VoWi-Fi)

Dual-mode phones (like some Blackberries) can use a wireless LAN to make a cellular phone call and switch to cellular when WiFi is out of range. My understanding is that in order to do this, you need not only the hardware/software, but your carrier has to support it (supposedly only T-Mobile is offring it in NA).
However I read somewhere, that with certain software like BeWip (http://www.bewip.com/en-us/info/default.aspx) the Kaiser can do it with any carrier.
Has anyone tried this? Can it be done?

Noone tried this yet?

x-series for our Kaiser

For all of us that use three provider, probably know that "x-series" option allow to use skype and let us to make call through a normal gsm call and not Internet traffic, using the iSkoot technology. Does anyone have the x-series software for our Kaiser?
I tried to make call through the normal Skype software or Fring, but the UMTS/HSDPA connection is not enough for make call yet...

3G/UMTS Issue with HTC Kaiser

Hello dear xda-developers.com forum!
Since app. 2 weeks I've got some strange issue with my HTC Kaiser:
If I set the Band/Network to auto, it's not possible to place phone calls or to surf over 3G/UMTS. If it's set to GSM (not to auto), I can surf over GPRS only and it's possible to place phone calls.
My provider is O2 - Germany. UMTS - option's enabled. UMTS-Sim-Card is used.
I upgraded to a Nothrill ROM with a new radio rom version - no effect. Same as before.
I hope there's no hardware-issue.
Eventually anyone can help me?
By the way: If auto - select is on (settings-phone-band, both values set to auto), the icon in the task bar shows that theres 3G available. If I try to surf with that connection, the Kaiser tries to connect with O2 interent - without success. But after that, the antenna-icon shows an exclamation mark and tells me, that theres no signal available....very strange thing.....
So, I hope anyone can help me,
regards and thanks for any help in advance,
Mario

Hi Many of us seem to have the same problem, its a hardware problem according to kilrah
Read this: http://forum.xda-developers.com/showthread.php?t=335074
Hardware problem, repair needed and unavoidable to get 3G functionality back.

My post is below.
--------------------------------------------------------------------------------
I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),
Radios tried
EMO 1.71.09.01
Neon 1.65.24.36
1.65.21.18 ( att )
I even loaded the generic dopod rom + radio and it didnt seem to help.
Is it possible something low level has changed whilst doing all this flashing ?
Or could the Hard SPL affect something.
I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.
Phone is Kaiser ( HTC TytnII )
ROM is varied but and usually lorentis series roms -- L26 12 light atm
Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.
If 3G icon not showing all calls and GPRS data works Okay.
Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......
The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....

HSDPA and HSUPA?

Can someone please clarify the difference between HSDPA and HSUPA?? I know HSDPA is the next one up from 3G in terms of speed, but am unsure of what the D and U stand for (guessing variants of similar?).
From what I can see HSUPA was not enabled by default on most older ROMS, but could be in the registry or using something like AdvancedConfig. However I notice that it is enabled by default on the latest Vodafone ROM (v1.97.x.4, a horrible looking branded ROM that I had to get rid of, but with some interesting 'latest and greatest' components hidden in there).
Lastly to sum this one up in my own context - a UK user on Vodafone - do I gain any benefit from having it enabled?
Thanks!

Wikipedia has a lot of info on HSDPA and HSUPA and the differences.
As for enabling it on the Diamond, someone else will have to help you

Thanks for the prompt reply. Indeed you're probably right - I could've used Google a bit more prior to posting.
To answer my own question / for the benefit of others:
They are both HSPA protocol implementations although achieve it using slightly differing methods, therefore while similar are distinctly different and not directly compatible.
It seems Vodafone in the UK has both HSDPA and HSUPA networks, therefore I guess it *IS* of benefit to have it enabled (potentially more chance of picking up a network signal faster than 3G).

The D stands for download and the U for upload. They are all part of the same service, just used for different directions of data travel. Some networks have one and not the other some have both.
Not absolutely sure but judging from the maximum upload speeds quoted by HTC for the Touch Diamond it does not support HSUPA anyway

Getting HD Voice on GSM/2G to work

When I'm calling someone and my phone switches from 3G to 2G due to better signal, the audio quality drops to standard quality, although my provider supports HD Voice on GSM as well.
My goal is to avoid this, by enabling the feature for GSM. The only problem is, I haven't found a way to do it, yet.
WB-AMR can be changed via the *#0011# Service-menu, but this only affects the UMTS setting not the GSM one.
WB-AMR can also be set by the CSC's customer.xml, but I can't seem to find a variable to do it for GSM.
My guess would be directly editing the modem and its variables via ADB, the file system or something like this, if that's possible.
Do you have an idea where to start?
