[Upgrading, Modifying and Unlocking] Shadamehr:
Right guys, a couple of things...

Pablo, you sure it's the ROM responsible. Might I ask, did you do a Sprite Backup based Restore of your data, to the device after Upgrading?

If so, the rest of us all know your problem - known bug with Sprite, if you restore Email and SMS settings, it corrupts your XDA and stops it receiving SMS. If this is NOT what has happened, then fair point.

Dataphd - like you, I find that the TrueFax application is a bit of a nightmare. When it does run, it won't send (the first thing it does, is to turn on a kind of flight mode on the phone to hog the line, but of course this then merans no coverage for it to send faxes - Doh!). Aside from which, like you, I had it hang the phone, AND require five repeated soft resets before my phone would work - a hairy moment or two there, I can tell you, thinking it was gonna need a full reset.

But let me explain something...

All I did, was take the extended ROM file attached in this thread.

Then I opened up my own extended rom on my device, with the tool now on this forum.

I backed it all up to pc first.

Then I deleted all the current files, and copied over, the new T-Mobile files.

Then, I never even reset, soft or hard, I just ran the 'autorun' file now in my device extended rom, and it set about installing everything.

And here's what I found:

T Mobile dialler skin, the pinky purple one, is the nicest I have used so far - it's based in style on the original dialler, but has t-mobile colours. The buttons however, somehow are much better colour graded, in that the origianl buttons show error diffusion. The new pinky t-mobile ones are lovely smooth coloured.

The new software is nice - a big improvement. The camera can now save images in bitmap format, as well as jpeg. There is a MMS video option (which basically is just the video recorder, but with all the settings fixed and pre-configured for MMS, in terms of file type, size, length etc.) The normal video mode can be accessed just the same through the camera utility of course though. The buttons are more intelligent now, in that instead of having to remember that to move from ohoto to video to fancy border template, you need to click the 'icon', youi now get TEXT with the word photo, and a double headed arrow next to it to signify scrolling through, this then changes (handily) to video, then the NEW mms video mode, then template mode. And the template mode itself is more intlligent, in that instead of having to keep tapping the same icon just mentioned to go through them all, and thus a long process to get back to normal photo mode, there is a SEPARATE double arrow option in this mode to go through any different templates you have, OR the normal double headed arrow for camera function to quickly take you back to normal photo mode.

The Caller ID software - before, I used Pocket Plus to ensure that when I close applications down, they really get closed, not minimized, but to 'protect' Caller Id, so that it never gets closed. I could tell this by running a program, choosing close all, and then re-running a new program, holding the x in to close all, and the caller id application would already be listed, as the last close of a program 'protected' this as it were - in other words, it would always be shown in the list of programs to close.

Now, even though I have checked that the filenames seem the same, when I close all programs (using Pocket Plus), Caller ID is not listed, BUT it seems to be running ok though, and still protected alright.

The fax program is dangerous - see above.

The zip application could be handy, but not really had much use for it yet.

And finally, two IMPORTANT things...

The connection settings are added to, in the form of all the new T- Mobile ones, which are easy enough to delete, as your old ones will also still be there, BUT, in terms of MMS, your existing actual server settings (that's the settings you can access within the MMS program itself, NOT the general system settings), get deleted, so I had to go back in and recreate the Orange MMS settings for my device.

And the last thing, and the one I am after advice on...

On all previous ROMS etc I tested, whenever I power up my device, or turn flight mode back OFF, the phone searches for a network, the arial bar 'hunts', and then it finds the network and the signal bar comes up, then GPRS is detected, a square G briefly appears to signify GPRS coverage also, and then the phone BEEPS to tell you it found a network etc, then the G disapears from the status bar, but can easily be checked by tapping on the signal gauge.

NOW HOWEVER, with the T-Mobile stuff on (and remember this isn't even a ROM upgrade, but just an 'over' install of the new stuff), I find that my phone, no matter what I do, no longer searches for the GPRS element of the connection any more. When I soft reset, or turn OFF flight mode, when the phone searches for the network, this is ALL that it does. It no longer searches for the GPRS connection too.

So the phone no longer beeps either to tell me it has found the connections.

Only if I manually do a GPRS connect, will it then 'find' a GPRS connection. Then If I disconnect form GPRS, it WILL remember that it is within GPRS coverage, by keeping the G symbol on the balloon that appears if you tap the signal bar.

Does anyone know how I might change this behaviour, so that the phone searches for GPRS automatically on switch on, as it is obviously just software related, as I have not done an actual ROM upgrade...

Cheers guys, hope this is of interest, and that someone might be able to help...
