Hi had some issues with my 3g on 3.13 had to muck about to upgrade to 4.0 and re jailbreak it however when I modified the host file I accidently deleted the whole thing (on obviously bad advice).Now iTunes cannot connect to the server. I've read some where that it is possible to rewrite the hostfile myself but I am no computer wizz and wouldnt know where to start. Does anyone know if it is possible to find a copy of the original host file txt and just copy and paste it with notepad and insert it back into the place of the original. PLEASE NOTE: I have already tried completely removing iTUNES and downloading and installing it again but no help.
