I'm about to install iOS5 on my wife's jailbroken (iOS 4) iPhone4. I've already backed it up. Do I need to do anything else before I install iOS5? Are all photos and contacts backed up?
Just remember not to install install Cydia apps "willy nilly" without checking it's IOS 5 compatible....and first thing you should install is SBSettings...
It would also be wise to back Contacts up in iTunes via the Info tab. It will have you back it up into a third party. I found the Address Book in Mac works best for me, and Windows Contacts on Windows.
