iOS 4.0.1 update breaks iphone 3G and 3GS

Why has the iphone gone slow since the updates to iOS 4.0.x ?

The iOS 4.0 update was recently delivered to iPhone 3G and Iphone 3GS users. Since the update many users are saying their phones now regularly lock up and take an eternity to perform basic tasks such as web browsing.

I have noticed a significant slow down on the Camera especially. Battery life seems to have gone worse.

While Apple does not permit people to downgrade to the previous version of iOS in iTunes, some sites have figured out a hack that allows people to revert to the older versions.

Apple said it recommended iPhone 3G owners update to iOS 4.0.1. It said anyone with issues could contact Apple on 133 622 or access their local Apple retail store.
