So i recently got myself a jailbroken iphone 4 and its running ios 4.3.3 im wondering if its possible to un jailbreak then upgrade the ios to 5.0.1 and then jailbreak the phone again? i looked on the cydia homepage and the only shsh blog i can see is 6.0.1. Totally new to this and its my first post so go easy on me. Thanks in advance
