Again Carrier says its been completed, and the carrier, AT&T, tech support says Apple's database is not updated yet, is the only explanation, in addition Apple phone Support says typical SLA once we get the request from the carrier is 1-3 days.... very vague
If your carrier has sent the request to apple, then provides you with a confirmation, and then you walk into T-mobile and slap in a new SIM card, and Apple hasnt processed that 1-3 days yet, your screwed without service
stick back in the AT&T SIM and run restore from inside itunes and itunes finds out from Apple's database that the device is ok to proceed as unlocked and does it for you. Or you can pay $50 per device for an online company to speed up the process, but we have 5 iphones on our plan... not cheap, best to validate FIRST
So again hopeing someone on here, somewhere has additional way to find out current SIM status like a status link like this one http :// iphoneimei. info but one that is free and actually queries Apple's database directly for current database activation status... I need all my phones validated unlocked before I walk into my next carrier and sign up without fear that we wont be without phones for the next 2-3 days.
