Since ur on BL3.9 then u should not be facing error 1015. Only people with BL4.6 will have this error if they try to restore to a firmware lower than they are using. 1015 means itunes can't flash the baseband as it failed the security checks. Maybe u can try manually flashing back your baseband. It's 2.30am and i can't think of any program to do this right now. Too sleepy to search my brain (what more google) for the program name. Maybe other forumer thats wide awake can help u with this. ZZzzzZZzzZZzzzZZ
