On my Curve, it was easy to delete multiple messages at once. I would simply hold down the "alt" key and the use the track ball to scroll down which highlighted several messages at once for deleting. This was VERY useful if you had alot of text messages with a friend in a short amount of time.
I can't find a way to do this on the Storm. So far, I have to delete messages one-at-a-time. Is there a better way to do this?
Press (not click) on the first one you want to delete and then with another finger do one on the last one you want to delete. It will highlight them all.
You can also click on any of the date headers and choose to delete prior.
