We tipped you guys off on Photoshop Mobile some time back, and now there is a Photoshop iPhone app, just like there is almost an app for everything under the sun nowadays. The good news is that it’s free (yay), though it’s only available in the US and Canadian iTunes stores. Folks will even be able to share their images via Photoshop.com, which allows up to 2GB of free storage. Of course, the iPhone app isn’t by any means a replacement for your desktop version of Photoshop, but if you want to get some quick editing done on the iPhone, this is probably the app for you.
