How To Jailbreak and Unlock iPhone iOS 4

Jailbreak, or “hacking” is giving a user read/write access to otherwise locked OS files on your iPhone.

It allows you to “unlock” your iPhone and activate it on another GSM carrier that doesn’t have bad Luke Wilson commercials. It gives you access to app stores like Cydia that offer programs that you won’t see in Apple’s popular counterpart.
