Apple iPhone users awaiting a jailbreak will be pleased to learn that further information has come to light on an untethered jailbreak for the iOS 5.0.1.

A few days ago, Pod2g, a member of the Chronic Dev Team, managed to successfully complete an untethered jailbreak for the 3rd-generation iPod Touch running on iOS 5. Now, Pod2g has managed it again and has successfully tested an untethered jailbreak to iOS 5.0.1.

While the jailbreak for iOS 5.0.1 was available last week, Pod2g has just confirmed the untethered version. Pod2g also tested the untethered jailbreak on iOS 5.0.1 and the results indicate it was successful. Pod2g tweeted on Monday that the untethered jailbreak works on iOS 5.0.1 and users can update immediately: Got an untethered iPhone 4 running iOS 5.0.1. Feel free to update.

Meanwhile, before users go ahead and look to jailbreak the iOS device untethered, it is important to note that the jailbreak has only been confirmed to be working on A4-based devices, such as iPad 1st generation, iPhone 4, iPhone 3GS, iPod Touch third and fourth generation. There is no confirmation that the untethered jailbreak works on A5-based devices like iPhone 4S and iPad 2.

Jailbreaking allows users to gain root access to the operating system, enabling iOS users to download additional applications, extensions and themes that are unavailable through the official Apple App Store. A tethered jailbreak requires that the device be connected to a computer each time it needs to be booted; an untethered jailbreak allows the device to be powered without computer assistance.

Another aspect to be kept in mind is that if users update their iPhones or iPads before the jailbreak update is ready, they will lose their hacked systems, reverting to Apple's version of iOS.
