I have tmobile as a provider NOT cingular. I unlocked these phones so I could use them with tmobile but I can't log onto ANY of the messengers on the phones. The only thing I can do is send/recieve texts and make/recieve phone calls. Is there anything that can fix this problem? I would like to be able to use all the functions that the phone has otherwise unlocking is a waste of money. I thought unlocking the phone would allow you to do this but apparently not. Please some one help who knows what they are talking about. Thanks!
