RedSn0w 0.9.12b2 contains the same Rocky Racoon exploit used in Absinthe 2. This version of RedSn0w offers two methods of jailbreak:

Backup/Restore Method (Applies to A5, A4 and older devices)
This method is pretty much similar to Absinthe jailbreak. you just need to connect your iPhone, iPad or iPod Touch and hit the jailbreak button on RedSn0w.
Your iDevice MUST BE activated (NOT stuck on Connect to iTunes).
There is no need to put your iDevice into DFU Mode.
DFU RAM Disk Method (Applies to A4 or older devices only)
DFU RAM disk method is preffered method if you have many songs, videos and other media on the device.
It requires you to enter DFU Mode manually (RedSn0w will guide you!).
This method is mandatory if your iPhone is inactivated.
