my iphone wont restore. i get an error 1603 what should i do?

try this page for solution possibilities:

http://support.apple.com/kb/TA38603?viewlocale=en_US

if none of those work i suspect it could be an issue in the hosts. lemme know how that page works for you 🙂

make sure to backup your data manually before doing so :]

also after you do the check for updates you should restart your computer immediately after.
