i have a 3g iphone and i am trying to restore it, but it gives me 1015 error, i am not a native english speaker and not so good with computers either, so i would appreciate if the help was as clear as possible, thanks

Please search before posting, this is a common problem with a simple solution that is documented all over the forums and the internet. Error 1015 means you did not put your phone into DFU mode while attempting to restore. Put the phone into DFU mode and attempt the restore again.

i also am having great difficulty with my iphone 3g, i tried to reset the phone and now it just has the apple logo on the screen and the loading wheel, but will not go any further. how can i get it to work? any help will be greatly appreciated,
