Apple today released iOS 5.1.1. As usual jailbreakers or those wanting to jailbreak in the future should wait before updating to the newly released firmware.
We'll let know what changes have been made once the Dev-Teams have had a chance to examine the firmware. Hopefully, the exploitst used by pod2g are still applicable.
MuscleNerd is specifically warning iPhone 4S and iPad 2/3 owners.
