I have the original MyTouch 3G (no 3.5 mm jack) running 2.2.1.
I wanted to know what it meant to "lock" a message. When you are in a text message thread and you long press a message, the first option is to lock it. what does this do exactly? where does it go once its locked? where can i see it? how do i unlock it after it disappears?

Thanks for any help
