Everytime I send a SMS I get a popup notification at the bottom of the screen and I have to hit "OK". I never had this before and not sure how I enabled it, probably through installing and uninstalling stuff. It looks like a WM6 notification and not a 3rd party thing.Anyway how do I disable it? Thanks

This is listed in the Samsung SCH-i760 FAQ at the top of the page. See here.

Got it. Thanks.
