I'm happy to have an android after years of fighting with my old Blackberry, but I'm bothered by one thing: I can't seem to find a way to customize WHICH notifications make noise! I really only want my phone to make noise for 2 things: I want it to vibrate when I get a text message and ring+vibrate when I get a phone call. Am I missing something obvious? Thanks! I have an HTC Sensation, new to me as of a few weeks ago!
