hi guys, apologies if this has been posted already, the thing is ive been having problems with my iphone 4 memory so i thought id try to re jailbreak it, but the thing is i have put my phone into safemode, even though i had the ios 5.0.1 i cant seem to get the phone to a fresh copy of 5.0.1 on it without itunes offering me a update of 5.1 which i dont want. Can someone please help me out? is there a way i can completely reinstall 5.0.1 and then i can jailbreak it later. I hope i made sense guys. thank you in advance.
