I starting to look into ios jailbreaking after I got my new ipad/ipad 3. From the research, to get jailbreaking on latest iOS 5.1 is become more and more difficult. Pod2g is one of the famous jailbreaker and is currently working hard to have iOS untethered version to be worked on all iOS5.1 devices. I’m following closely on his twitter news on any of the news release. The untethered iOS5.1 seems has been working properly and fine from his tweet. None of the untethered iOS5.1 is available yet for public but it will going to release very soon to you, said pod2g.
