Had a weird bug today using 3.2.
I was composing a new text message, manually switched to landscape via long press talk key, and while I was writing the message I got a call. I could tell because the lights on the dial went all crazy.
Problem was nothing was displayed on the screen, and the text message screen was frozen. I could mute the ring with the side volume buttons, but I did not regain control of the phone until the call went to voicemail.
Kind of a lot of circumstances to happen at once.. but it happened nontheless
Just trying to be helpful!
