Following last week's ruling by the US copyright office that made jailbreaking iPhones legal, the first jailbreak for the iPhone 4 has appeared. The new jailbreak is browser based and while it works there have been some reported cases that certain features such as FaceTime and MMS don't work with it.
The successful hacker known only as "Comex" is said to be a member of the iPhone dev team and launched the hack on jailbreakme.com, accessible through the iPhone's Safari browser. The website subsequently crashed due to the stampede of people wanting to jailbreak their phone. The problem has been fixed though with the help of Jay Freeman aka Saurik providing a second site, jailbreakme.modmyi.com, to handle the load. Saurik is well known for working on Cydia for jailbroken iPhones.
The site makes the process of jailbreaking easier than before when software was required, now all users have to do is go to jailbreakme.com and follow the instructions, it's all done through the browser. And its not just the iPhone it works on, it can also be applied to the iPod touch and iPad, although it won't work on the iPad's iOS 3.2.1.
The jailbreak is free, though anyone who uses it is invited to make a donation, and the site comes with the reassurance that the jailbreak can be reversed if the user is worried about damaging their iPhone.
