Final version of iOS 5 is just around the corner and until now, a host of iOS 5 Beta releases have taken place. The latest version of this OS for iPhone, iPod Touch, and iPad includes many new features and enhancements over the previous 4.x.
Until now, there has been no untethered jailbreak for iOS 5. If you want to jailbreak, any of the Beta releases of iOS 5, then you could opt for either Redsn0w or Sn0wbreeze. However, you would only get a tethered jailbreak. Only users of iPhone 3GS with an old bootrom are lucky enough to have an untethered jailbreak. Rest of the iOS devices are not so lucky.
A tethered jailbreak is a temporary one. Once you reboot your device, it’s gone. You will have to connect your device to your PC and run the jailbreak tool once again. This is why an untethered jailbreak is always the preferred choice of a jailbreak for most iPhone users.
Fortunately, we hear some good news coming in from a member of the Chronic Dev Team, pod2g. This is the same iPhone hacker who earlier discovered an untethered jailbreak exploit for iOS 4.2.1 and iOS 4.3.
According to his tweet, the Chronic Dev Team, creators of the GreenPois0n jailbreak tool for Windows and Mac, are actively working on an untethered jailbreak for iOS 5.
He also confirmed that there would be no untethered jailbreak for a Beta release of iOS 5, as this would give away much of their hard work to Apple easily.
Apple is expected to release iOS 5 to the public sometime during the last week of September 2011. All iOS 5 betas released so far are meant only for developers of iPhone apps with a subscription to the Standard or Enterprise program, and are not available to the general public.
