“Double Flip” to Launch Gesture Search
This seems pretty cool. Basically it lets you search for a contact or (anything else) on your phone by writing the letter on the screen but it lets you access the "Gesture Search" by flipping your phone away and then back. I have installed it and it's indexing my contact list but in my preliminary messing around it seems to work. Check it out.
EDIT: Ok... The actual "flip" to start the program doesn't seem to work for me but the Gesture Search is still cool (starting it with the icon). Maybe they will fix it up for the Vibrant soon.
