As we pointed out before, the newest jailbreaking tools should be approached with caution at the moment. Developers and industrious hackers alike are working to introduce tools for jailbreaking Apple's devices as soon as a new iOS version is released.
The new iOS 5.0.1 update already has its own jailbreaking solutions, however, interested users should proceed with care, TechSpot (opens in new tab) reports. The most recent versions of redsn0w and sn0wbreeze are available for iOS 5 and even promise to work for devices running on iOS 5.0.1, with the notable exceptions being for iPhone 4S and iPad 2.
The aforementioned solutions only offer a tethered jailbreak though; this means that users have to reconnect the jailbroken iPhone or iPad to a computer running a jailbreak utility when the device is restarted, or the device will not boot into iOS successfully.
On the other hand, BigBoss announced at the end of October a Semitethered Jailbreak. The patch tool takes care of the problem, but only partially. Advertised to work even on iOS 5.0.1, SemiTether allows users to have more freedom and the connection of the jailbroken device to a computer is not required. However, the functionality is limited; the Mail app, mobile Safari might not work properly, as well as some apps and Cydia - in which case you'll need to perform the normal tethered jailbreak.
