We've had a Photoshop app available to our iPhones for a while, but now we can finally do some crazy image editing on our iPads as well. The app is free, comes straight from Adobe, and is called Photoshop Express.
The iPad app is actually a version of the Adobe Photoshop.com Mobile app that was available for iPhones. It's simply been renamed and turned into a universal app—meaning that you can use it on your iPhone, iPod Touch, or iPad. [9 to 5 via iTunes]
