I was cleaning out my closet and found my old g1050 from when I was a customer of Digiph PCS (which was bought eventually by T-Mobile).
It is apparently a 1900MHz device. The phone still works great and surprisingly still keeps a charge. I really liked this device and would love the option of using it on AT&T (if nothing else, for the nostalgia).
Does anyone have any idea of how I could get it on AT&T? I put my SIM in and it says "Card Disabled".
In case you're still trying to get your g1050 onto AT&T, I just got mine onto T-Mobile. The handset is locked and will need to be unlocked. T-Mobile unlocked mine by sending me the code via email. Mine used to be with Omnipoint, but I imagine the codes are the same.
