IF YOU FANCY escaping from Apple's walled garden, Greenpoison has the answer with an untethered jailbreak hack for Mac and Windows.
Working for IOS 4.2.1, the current version of the operating system used on Apple's Ipad, Iphone and Ipod touch devices, this jailbreak is different from ones we've seen before. Previously, every time you rebooted your device you would have to connect it to your computer to start using it again.
This was quite an issue if you weren't near a PC, as your Iphone would basically be dead once the battery ran out. But the latest versions of the jailbreak released this weekend for Mac and Windows, but not yet for Linux, have got over this problem.
Whenever criticism of IOS devices comes up, the fact the company closes it off is a stick used to bash it repeatedly. But jailbreaking now is perfectly legal, even if Steve Jobs would give you the evil eye for doing it.
There are perfectly valid reasons for doing it. There might be apps you can't buy in the App Store, or maybe you want to give your older device a bit of extra functionality and pep.
As with all tools like this, you jailbreak it at your own risk and you could void the warranty. It might not even work. But in the majority of cases, just like with Android devices, putting the device back in its original state is usually easy to do. µ
