Apple released the first beta of the upcoming version of its mobile operating system (OS), iOS 6, just a couple of weeks back, letting developers have a firsthand look at how the software will behave. On Monday, the Cupertino company pushed out the second beta of the OS, iOS 6 beta 2 build 10A5338d, to developers as an over-the-air (OTA) update with a wide variety of bug fixes and slight improvements.

If you are a developer and running iOS 6 beta 1, you can download the second beta of iOS 6 via OTA update by heading over to Settings > General > Software Update. The iOS 6 beta 2 build 10A5338d for iPhone, iPad and iPod touch is also available on iOS Dev Center.

Once you install the update, you will notice a few things that have been changed. The very first thing you'll observe is that the gears on the installation icons are now spinning. Another thing would be the added full change log, Jailbreak Untethered reported.

According to iDownloadBlog, Apple has re-added the Enable 3G toggle in the Settings app in the iOS 6 beta 2, which was noticeably missing in the first beta. This will allow users to turn off their device's 3G data when in a poor service area, or when trying to save power.

If you've updated your iPhone 4 (GSM/CDMA) or iPhone 3GS to the iOS 6 beta 2 firmware, you can jailbreak it tethered using latest version of the popular RedSn0w jailbreak tool. The iPhone Dev Team has released RedSn0w 0.9.13dev2 to address issues with SSH and app crashes, experienced by some users before.

Update #1: The 'dev2' version should fix the various SSH problems and crashes with apps that some have been seeing, read a post on the iPhone Dev Team's blog.

Before going ahead with the process, you must note that to download iOS 6 beta firmware, you need to have a developer's account. You also need to have the iOS 6 beta 1 firmware in order to jailbreak iOS 6 beta 2.

As Redmond Pie noted, you will need to 'point' RedSn0w [0.9.13dev2] in the direction of the older iOS 6 beta 1 firmware in order to spoof the jailbreaking tool into freeing up your device.

In addition, this jailbreak will not install Cydia. Users will need to do that manually. For more information, click here.
