[Update: for iPhone 3G users, you can see how to unlock the iPhone 3G with a Sim Adapter]
Have you ever wanted to break the rules? are you interested in the freedom of cell phone carriers? or maybe you just want to know how to unlock it yourself. For whatever reason, some of the methods to unlock the iPhone are available to all. Three ways to unlock your iPhone may be found through Business 2.0. Any of these used are at user’s discretion, responsibility, and could be dangerous. The latter due to a recent story of an unlocking hack gone bad ending up with an exploding iPhone (Gizmodo). Luckily no one was hurt.
