I have an iPad 1 on 4.3.3 jailbroken, and I'm considering on upgrading to a 5.* iOS. What are your experiences on either and which one would you recommend? I know that the 5.1 JB is tethered, but it's no big deal in my situation on this. I just need to find out it's worth more upgrading to either. I appreciate your comments. Aloha!
