Apple iPad jailbroken in less than a day

The iPad has been hacked almost immediately

Apple's iPad is selling well but hackers have been busy and the new device has already been jailbroken, according to postings online.

Yesterday Twitter user MuscleNerd posted a video and picture of what appears to be a jailbroken iPad, credited to a hacker known as 'Comex'. Comex is a member of the iPhone Dev team, which has also said that a jailbreak is possible but has yet to release it.

Both attacks appear to depend on the use of a variant of the Spirit application that is used to crack iPhones.

Apple is playing a continuing game of cat and mouse with those who seek to use their own software on the devices they have bought. In the past updates have rendered devices useless, and Apple has banned some users from its App Store.
