My iPhone 4 has the option to install iOS7 but I'm not too sure if I will like it. Is there anyway at all to revert it back to iOS6 if I want?
Can you revert to iOS6 after installing iOS7?
I believe so. But the only way is if you backed up your iphone on your computer while it was iOS6. Everything since you last backed up will be wiped but you will have iOS6.same with game updates ect.
