Now on iOS 4.1 for my 3GS. So far, so good... speed is faster than 4.0.2 any time but much more stable. Previously on 4.0.2 will lose 3G connection and have to restart phone. Now, don't need.

However, still slight sluggish when compared to 3.1.3 last time.

Decided to give up connecting iPhone to car HU. Each update breaks the compatibility. End up buying a 5th gen nano instead. Problem solved.

Deleted all the audio and video files and got over 24GB of free space.
