Hi I tried to update my JB iphone 3g from 2.2 to 3.1 and things went really bad so I restored my phone through itunes. Now I am on 3.1.2 and carrier is 5.6. Can I JB again and if so how? I don't want to unlock now just JB so I can use lockinfo, cycorder, snapture and anyring. Will all this cydia apps work.
