These two worked perfectly for me on my JB 3G on 3.1.2 until a couple of days ago. I think the recent 2.0 version of 3g Unrestrictor messed it up. Tried the new 2.0.1 version also without success. In searching around the boards, it doesn't seem to be a common problem. Has this happened to anyone else? anyone know who to get the old 1.0.7 3G Unrestrictor version. The only one available on Cydia is the newer version.
