Hacker @Pod2G has tweeted out 3 tweets about the iOS 5.1 untethered jailbreak as well as the A5 and A5X jailbreak yesterday. Seems We are just weeks away from untethered jailbreak for iOS 5.1 to be released, but a little longer for the A5 and A5X jailbreak.
Keep in mind that this news only pertains to the iOS 5.1 jailbreak for A5+ devices. Other users may not have to wait quite that long. The A4 processor, as always, is susceptible to GeoHot’s Limera1n bootrom exploit. So it’s really just a matter of creating an untether for those devices.
Regardless, if you haven’t updated to iOS 5.1 yet, we recommend that you stay away from it for now. Especially if you want to keep your [untethered] jailbreak. There just simply aren’t enough new features in 5.1 to justify losing all of your favorite tweaks and themes.
We will keep you updated, stay tuned.
