Not usefule yet.
Then I disconnected the phone and noticed it became very slow. Hence I rebooted it, and it never booted up correctly afterwards. I got the animation with the hands, but never got the home screen. I was able to enter the menu though, but the phone remained very slow and unresponsive. I tried removing the memory card, and boot up that way, but no luck. What I noticed after pressing the Home screen for the running tasks, there were lots of open tasks with puzzle icon (they filled up my screen)... Somehow I managed to enter the Application Manager and removed the Maps application (considering that was the only app I refreshed using the beta Nokia Suite) that did not help either.
I did a factory reset on the phone, but afterwards I was not able to connect the phone again with the beta Suite. It failed to install the necessary drivers on the phone. Hence I removed the beta app and installed the latest GA Nokia Suite.
