A couple of times I've gone in to my messaging screen and did something (touch the contact's icon, I think) that actuall called the person. When I do this, it just puts a phone icon up in my status bar and I can't figure out how to cancel the call....I don't even hear it ring or anything until the person picks up.

Is ther any way to cancel the call when I fat finger like that?

 

It hasn't done this for me. IIRC, it just stays on the message screen and puts a green phone icon in my status bar. When I pull down my status bar, I don't see anything clickable to bring up the phone. I guess I'll have to play with it when I get a chance.
