I have a 3GS 3.1.2 jailbreak and wanted to upgrade to 4.0. I no longer want to keep my jailbreak. If I simply update to 4.0 on itunes will that fix everything or do I need to do something to remove blackrain/cydia and all that stuff from my iphone.
Sorry im new to this just want to make sure if I simply update from itunes that it wont mess up my phone..
