Is there a way to delete text messages in one big mass or do I have to delete them one by one every time?

highlight one, hold the "shift" key and scroll your trackball to the last one you want to delete, this will highlight them. Then Menu> delete

[jm2hill]

roll over a date hit the menu button and click delete prior

Does delete prior delete all messages or those prior to where the track ball is positioned?
