It didn’t take long for the hacker community to identify a way to jailbreak iOS 4 and the iPhone 4. In fact, they’ve made it so easy to do so this time around that you don’t even need to connect your iPhone 4 to your computer to complete the jailbreak process.

Utilizing a security vulnerability in the way that the iOS 4 handles PDF files from applications on the iPhone, the community was able to create access through Safari and a website they’ve build just for this purpose, jailbreakme.com. Starting the jailbreak process is as easy as visiting that site and following the on screen instructions.

An iPhone is jailbroken in order to allow users more control over what their iPhone’s user interface looks like, access to additional applications that Apple hasn’t approved for sale through their App Store, and configuration settings. Many iPhone users maybe interested in jailbreaking their phones in order to add functionality like tethering your iPhone internet connection without having to pay AT&T an additional $20 a month.

Jailbreaking an iPhone is completely legal. In fact, just recently the government specifically called out the ability to jailbreak phones and highlighted that it was exempt from copyright infringement and is legal. While jailbreaking the iphone is legal, it is important to note that Apple will void your iPhone warranty if they can identify that the phone was jailbroken.

  2. Navigate to Jailbreakme.com
