iPhone/iPod Touch 2.0.1 not perfect

Nu har jag uppgraderat min Touch till 2.0.1 men blev besviken. Problemet jag haft med att de nedladdade applikationerna från App Store inte startar kvarstår. Nån som har nåt tips?
I have now upgraded my Touch to version 2.0.1 but I am disappointed. The problem I had with downloaded apps from the App Store not starting is still there. For example Facebook, Remote and Twitterific. They load the first screen but then they crash.
