Text messaging Force Close issues after OS upgrade I upgraded my Samsung Galaxy S GT I 9000 to Android 2.2 yesterday...but I just can't open my messages...it says Force Close every time I try...any solutions?? 

If not, how can I downgrade to the original 2.1 Eclair?
Try clearing the cache of the Messaging app.

From the home screen:

Menu | Settings | Applications | Manage applications | All | Messaging | Clear cache

If that doesn't work, I'd try the following, in this order:


Force Stop
Restart the phone (off then on)
Clear data (will likely lose your SMS messages)
