How unsimlock Iphone 4s in IOS 7
Hi, I asked my provider to make the first steps to unsimlock my iphone 4s. Got a mail I can continue, but their assistance is not updated and the procedures advised in Itunes don't match.
Is it that simple: make a backup in ITunes first, then to setting/general/reset/ erase setting and content and restore by ITunes? 😕
Thanks.
iPhone 4S, iOS 7.0.2
