I got one:
Cannot changge rigntones
Cannot find games
Cannot find 850 settings
Cannot access the web
I have tried with both a Cingular 850 SIM and a T-Mo 1900 SIM as the phone is unlocked.
It makes calls and does text messaging just fine.
Any help would be greatly appreaciated. Thanks
Call T-mobile to get it unlocked, tell them that you are going down to mexico or somewhere and you need to put in a non t-mobile prepaid card, and that you want to use your phone down there, and they will give you the code to unlock it to use it with other sim cards.
Just make yourself sound convincing
