Just an FYI for those of us with the Samsung Galaxy Tab--it already does this. I've taken a bunch of panaramic pictures using my Tab. Apparently, it supports horizontal as well as vertical panoramic (you can move side to side, or up and down for vertical panoramic images... like the time I took a picture of the tallest tower in Hartford, CT, the Cityplace Building). You can get it by going into the Tab's camera app, tap the "screen" icon (top-left side of the screen) and you'll find several modes: Single shot (default), Continuous (takes pictures for as long as you hold the snap button icon), Panaroma (WHOO!), Smile shot (yup--snaps the picture when it detects a smile on the subject), and Self-shot (uses the front-facing camera).
