unlocking a flip phone - cust serv rep said "you can't"
Switching from AT&T to TMobile. 2 lines ported easily. My mom has a Tinno U102AA (Cingular) flip phone. It's asking for a NCK code (18 digits, I believe). NO ONE at AT&T knows what I'm talking about. In fact, the last cust serv rep told me (while she was laughing), "flip phones, this one included, can't be unlocked." After spending 1/2 my day on the phone with AT&T and TMobile cust serv reps, I couldn't find the words to speak and just said, "thank you"...and hung up the phone. The phone is in the "process" of being unlocked (it's been 4 days) but who knows if I should just go buy my mom a new/unlocked flip phone. Where can I obtain the NCK code (Network Control Key)? And can the Tinno phone actually be unlocked or am I wasting my time?
