iPhone 4S owners with a jailbroken iPhone can now unlock the iPhone 4S at home using Sam Bingner’s SAM package on their own.
The SAM (Subscriber Artificial Module) package allows user to unlock a jailbroken iPhone 4S to work on T-Mobile or another carrier’s GSM network.
The iPhone unlock tool works on all jailbroken iPhones running iOS 5 and higher.

The iDownload team is now able to switch back and forth between SIM cards to switch carriers at will, without the need to configure any additional settings. This is helpful for users who want to use AT&T in the U.S. and another carrier while traveling.
The new iPhone 4S unlock tool only works on jailbroken iPhones, which means it will not work on an iPhone 4S running iOS 5.1. Users with a jailbroken iPhone 4S or iPhone 3GS, can use this tool with the current iOS 5.1 jailbreak, but it is only a tethered jailbreak.
The iPhone unlock process isn’t a one tap deal, but most users can follow the 9-step iPhone unlock process. Users should save their Activation tickets in the event users need them.
Before undertaking the iPhone unlock, be warned hat some users cannot activate their iPhoen after performing some of the unlock steps.
Though unconfirmed, the unlock is unlikely to work on Sprint or Verizon iPhones.
