What date can I unlock At&T Lumia 920?

[SecretFire4]

Bought an Cyan At&T Lumia 920 off of craigslist. Currently using it on prepaid, but hopefully going to go on tmobile. Does anyone know the date that At&T Customer Care will be able to unlock them? I heard from somewhere that the date is somewhere is in May. Can anyone confirm/deny this?

Not heard a official date yet but it should be in the next month or so.

i believe AT&T will provide unlock codes on may 9th or 10th. but its for only for people who paid in full value. for rest of the folks its based on account standings and luck

I confirm this. I called to AT&T customer service, today at morning and got the unlock code. This guy just asked for the IMEI and gave me the code. Now my Lumia 920 is using t-mobile network
