A hacker claims to have "jailbroken" the iPad 2 just three days after its US release, allowing users to run unauthorised software and programs other than those provided by the App Store/iTunes. A hacker calling himself Comex began boasting of his feat on Twitter, before posting video evidence of his achievement. The video shows a white iPad 2 running Cydia - an application used to find and download other apps for iOS devices. If the iPad 2 has been jailbroken it should theoretically be able to run any compatible software. "Would've had it yesterday if I didn't have to spend 1.5 days looking for a replacement exploit (which came from a most unexpected place...)," said Comex on Twitter. Three days is actually one of the longest waiting periods for an iOS device to be hacked, with Apple having removed some of the more obvious vulnerabilities with the release of the new iOS 4.3. The iPad 2 is not released in Europe until March 25, the same days the 3DS. Nintendo's device has also reportedly fallen prey to hackers, with a variant of the R4 cartridge apparently already in use. The company has warned that it will release firmware updates to immobilise (or "brick") any console found to be using pirated software.
