Sorry but please don,t consider this a "re-post". I need help with this problem and i probably didn,t explain it too well on my first post. I had my phone unlocked and jailbreak ,from 4.3.5 off Vodaphone network,now on 02. to 4.1 (8B117) Now when connected to i tunes i get "error 0xe80000001". i was given advice to put it into DFU mode, this i did, then it asked me to restore, then update, i did not proceed for fear of losing my jailbreak and unlock , have you got any idea of what i should do to solve this problem, if indeed it is solvable . Thank you for your patience.
