The Jailbreakme hack is out to open up our iPhone 4 (or for that matter most iDevices running the iOS 3.x and 4.x). Apparently this hack uses a security hole in the iOS browsers PDF viewer and manages to install Cydia on your device by just opening a website. Cool, but be warned there can be malicious codes running on the WWW who can use that hole for deadly hacks.
For the moment the image above shows some adventurous guy – jailbreaking the iPhone 4 at an Apple store. 😀
