That little hole in the back of your phone takes decent photos — from time to time. For the ones that don't live up to your standards as a newly minted shutterbug, a little editing can go a long way.
While editing photos on a cell phone isn't exactly anybody's idea of a good time, Photoshop Express makes it pretty straightforward with a nice mix of tools you'll actually use. You can upload edited photos to Photoshop.com to share them with friends and family or send them off to Facebook instead. There's Twitter integration too.
