Hi i have a jailbroken (jailbreakme) iphone 4 on ios 4.0 (8a293) baseband 01.59.00 I would like to upgrade to any version of ios 5 as I am unable to use many apps that require at least ios 5 after reading many tutorials I am unsure whether it is possible to do this obviously I would like an untethered jailbreak. I am confused about unsigned ipsws and whether it will still work I am concerned I will not be able to restore all my jailbroken apps iPhone3,1 2885515019021 remote blobs:
