Is this possible or am I crazy!?!?!

[angrytaxman]

I just started service with T-mobile. I also just bought an AT&T SX56 on ebay because it was cheaper than the T-mobile version. So is it possible to unlock the phone and use it on T-mobile and still have GPRS functionality? I'm pretty sure that part is possible, but now I want to throw a wrench into the gears. Could I then upgrade to a T-mobile ROM and radio stack on the AT&T phone? OR could I be even crazier and use a T-mobile radio stack on the new official WM2003 release by AT&T? Sorry for all the weird questions, but I'm just curious as I'll have my phone during the early part of next week.
Thanks for all the help,
Danny

an xda is just like any other phone when it comes to the posiblity of changing network and getting gsm services like wap and mms and grps

first your phone need to be unlocked that is if it were locked to begin with

then you need to set up those services
how you go about doing so somewhat depend on your network provider

an std way of doing it is
enter settings
enter connections
enter connections
add a connection if non are present
otherwise maybe you have to edit a present one
choose celluarphone(gprs) or something like that
type in the access point of the network provider
often it's just "internet" but otherwise contact the
network provider as to what they use
and of cause if they ofer grps at all and if it's turned on
and then you press ok a few times
and end back at the today screen
then you open something like IE
and it should give you a login and password
page
many networks dont use those and you can just
leave them blank and press ok
ask your network provider
and then you should be online with grps

100's of people have asked the same questions and those
questions are most of the time in the forum called network
100's of people have answered those questions
so if you have more issues i'm sure that searching in that
forum will give results
