The Evad3rs team have been hard at work and they have updated the Evasi0n tool to jailbreak iOS 6, 6.1 and 6.1.2 with improved boot times. Some users had reported that their boot time was considerably longer after jailbreaking using Evasi0n. If you have already jailbroken your idevice you don't need to do it again. All you have to do is check within your Cydia packages for the updated list which should be available after a refresh.
News has spread that Apple has plugged one of the key exploits used by the Evasi0n tool to jailbreak all A5 devices running iOS 6.1.3 beta 2 and it looks like the release of iOS 6.1.3 will be a task that even the Evad3rs team won't be able to beat. Planetbeing has already stated that it one exploit is down the whole jailbreak is finished, so if you do want to keep your device jailbroken the advice is not to update your firmware.
If you haven't jailbroken your iOS 6 yet and you would like to do so, you can download Evasi0n for Mac, Windows and Linux. For those who prefer the familiar jailbreak tool known as Sn0wbreeze, you will be happy to hear that it has also been updated to Sn0wbreeze v2.9.11. Last week this tool was updated to v2.9.10 and this new update fixes a bug with the compatibility issues with Cydia that was found with the untethered package on 6.1.2. Sn0wbreeze v2.9.11 is compatible with A4 devices only so if you have a newer model iPhone you will need to use Evasi0n to jailbreak.
