I've recently joined the iPhone cult, finally laying the 2 year old Nokia premium go-phone to rest. I'm not big on filling my phone up with alot of stupid games and apps like "ghost tracker" or a "fart app" (yes, that's a real app), however one worthwhile application that I've stumbled upon is Photoshop express. This app takes the very basics of Photoshop and puts them at your fingertips. You can edit photos on the fly right when you take them or you can choose photos from your camera roll. It really does an awesome job at doctoring up your pictures on an already awesome picture taking device. The best thing about it is that it is, surprisingly, a free application. Basic tools but its a good way to doctor some photos if you plan on sending them via text or uploading straight to Facebook or Twitter.
