Press "delete" continuously and see if respond.

Hi,

Go to your inbox, click the options button (a white square with three parallel gray lines) as usual. Do not select "Delete" but "Mark/Unmark". Check the box on the top left hand corner and your phone will select all but the first message (you can avoid this by first unchecking the first message or checking the first message separately with a second touch) then touch "Delete at the bottom center of the screen". Your messages in that folder are deleted permanently.

Hold the delete key down longer than usual until the menu says "Delete all Calls?"
