The tools users need to jailbreak Apple’s latest smartphone have been released. This allows users to run software that hasn’t been authorized.
The iPhone can run third-party software, but only apps that have been approved by Apple. There are many who think this is too restrictive. A group of these people who are developers has released a version of the purplera1n jailbreaking tool for the iPhone 3GS.
A device that has been jailbroken can run unauthorized software — this includes unlocked apps, which let this device be used with any GSM network.
Getting the Tools
There are versions of purplera1n for both Windows and Mac OS X, and these can be downloaded from purplera1n.com.
There are also versions of this tool for earlier Apple smartphones.
Anyone considering jailbreaking or unlocking their iPhone should keep in mind that doing so is completely unauthorized by Apple. They should also be aware that Apple will do everything it can to break the unlocking tools with future versions of the iPhone OS.
