When you are searching for custom firmware for A5 devices such as the iPhone 4S and the iPad 2 it was hard to go past the brilliance of the Pwnage tool. As far as I know the Pwnage tool was the first tool that came out for A5 devices which would allow people to keep the baseband. Now of course you can use the Sn0wbreeze custom firmware as well if you wish. It all depends what firmware you are running on your device.

If you did already upgrade to iOS 6.1.3 luckily the team over at Sn0wbreeze managed to come up with a solution so that you can jailbreak it. This is the guide to jailbreak iOS 6.1.3 with Sn0wbreeeze.
