Is there a T-Mobile Modem that will work on i777?
I have an i777 that was unlocked with Siyah. It obviously was an old AT&T phone but I'm trying to use on T-Mobile.
I know that there are physical differences with the radio that won't allow it to get more than a 2G data signal in most areas on the EDGE network. That would be fine if I could get any signal for voice, texts and 2G data but I don't get anything.
The phone only wants to find AT&T towers and will not ever show T-Mobile signals.
I assume that I need to flash a T-Mobile modem but they are all for the T-9898 and not the i777 or i9100.
I would appreciate any advice.
