i updated my iPone 3G yesterday and ever since then it has been REALLY slow. everything lags, not just using the internet. When I text, my keyboard is slow and only picks up half of the letters i type.it takes forever just to open any app. is anyone else having this problem?
Mine behaved similarly with sluggish performance, so I restarted the iPhone. Then I had an issue that others have been having where the 3rd party apps crash. So I decided to restore from scratch. It was successful.
The iPhone is now fully functional running iOS 4 (less the features not compatible with the 3G). It has no unusual lag and everything I've run works normally.
