im all kinds of confused
well, let me start from the beginning.
I got an iphone off ebay, said it was unlocked, it wasnt (jailbroken instead)
due to some stuff i was doing with iOS 6 i had to wipe and restore back to 5.1.1, i called AT&T, they said my phone wasnt unlocked and THEY wernt the ones to unlock it. Si i called Apple, and they told me that the Carrier (AT&T) has to do the unlocking. anyway, nobody would do it for me. so i Jailbroke and unlocked it thrugh a Cydia app, it works ( as long as i dont Software Update) so i used it for a few weeks, was playing around with installing SiriPort, and got the "Stuck on Apple Logo" screen, so i turned it off, held home button while plugging Sync cable in, it entered Recovery mode, and after it wiped and reinstalled ( back to unjailbroken 5.1.1) it iTunes popped up and said "Congratulations, your iPhone has been unlocked", so i was a little skeptical, i used the link above to check my IME # and it says it is still locked. and when i go to Settings > General > Network, there is no place to put in my Carriers Info (StraightTalk). so if somebody could help me out, that would be awesome.
iPhone 3GS
iOS 5.1.1
