Hey so I just got my iPhone 4 and want to jailbreak. i'm on 4.0.1 but just had a couple of questions before I do so. First off, is there anything I should do before or after I jailbreak my phone. So far I've just made a copy of camera+ because I dont want to lose it if something goes wrong.. I also heard that its a good idea to save SHSH blobs. But is there anything else i should do just in case something goes wrong? Any advice would be greatly appreciated.
