So, I started service w/ T-Mobile and they had to give me a loaner phone (1st gen Windows phone
) because ATT has yet to unlock my HTC M8... When I go to the unlock request page on their site, it doesn't recognize the IEMI. I was on hold w/ ATT for over an hour while waiting at the Tmo store and ATT said once the phone # is ported, the phone would be available to unlock. It's been 2 days. Their customer service reps don't have an answer for me. If anyone here is familiar with this, please advise. I feel like ATT is giving me one final f-you as I leave. What a nightmare they've been.
Edit, finally got an unlock code from them. Will try it out today (fingers crossed)!
