Apple made it in such a way that unlocking some basebands is very hard. The prime example comes in the form of 4.11.08 though now ApplenBerry and R-SIM 4 may unlock it soon.
Recently, an AT&T user sent an email to Tim Cook, Apple's CEO, stating that the carrier wouldn't unlock his iPhone with international SIM cards. AT&T doesn't usually unlock their locked devices even after the expiration of the contract. But Cook's office instructed AT&T to take care of this customer.
More people are known to be emailing Cook (email@example.com) in hope to try their luck after reading the news about the customer.
9to5Mac stated that Tim Cook gave special orders and 6 more people for their iPhones unlocked. Like the above mentioned customer, they all got an email from Partnership Operations Team. For further processing, AT&T's operations team asked the people to provide IMEI numbers.

Hold your horses; there are some things you should know! First you should try this only if you have an iPhone from AT&T. Secondly, write an effective email. Third, keep calm! If you are eligible and follow these instructions, you might get lucky!
We know many are stuck on iPhone 4 with locked to AT&T. Some are on baseband 4.12.01 which came with the new iOS 5.1 while 90% are on 4.11.08. Everyone mentioned that they included the point while emailing to the CEO that how frustrating it is when users are unable to use their iPhone outside US.
