Just installed Photogene[SUP]2[/SUP] and I must admit it's a cracking little app if you like using your iPhone as a Camera. You can take photos directly from the app, and it has a whole host of photo editing functions....I haven't even begun to scratch the surface of what it's capable of. It's currently only £0.69 ($0.99) from the App Store, but only for today, so get it quick!!!
