From your INBOX:
Select menu
Select tools
Select options
Select the gmail account
Select accout setup
Tap next 5 times this should put you on the screen that has “Automatic send/recieve:" at the top
Select “Advance settings” located at the bottom of the screen
Drop down box under “when deleting messages:”
Select one of the two options (Move them to trash or delete them off the server)
Tap done and your all set

Hope this helps. There is no option to keep the message in your in box on the server but at least its not totally deleted. Just remember to start from your inbox not on the sense tab or you will not get the same menu options
