Pod2g actively working on it
Untethered jailbreak for the recent iOS 5.1 is being researched actively by the well-know French hacker Pod2g
As you sure know, Apple released the new version (5.1) of the popular iOS for iDevices the last week with all the known vulnerabilities that allowed jailbreak fixed. As for know, there is only the tedious tethered or semi-tethered jailbreak for A4 devices with no luck for A5 users (iPad 5 and iPhone 4S). Anyway, Pod2g confirmed on Twitter that he is working actively to bring a full userland untethered jailbreak for both A4 or A5 devices the same way he did with iOS 5.0.1.
It's a matter of time that the trick will be available.
