So I got sick of looking at low resolution icons and images on my iPhone 4 (yay Retina) and started making high-res versions of images for apps that I use commonly. I'm decent with photoshop and have used images I've found from the web and a retina-GUI and icon PSD template I found to create them. Obviously I don't take full credit for any of these (though I did make adjustments to all of them, none were taken as is) as they're pieced together from multiple sources, so feel free to use them at your will on you phones.
Sorry for the large size of some of them, but they're in they're original resolution.
If anyone needs help placing these images (but already knows how to SSH, there are plenty of good tutorials for that) just ask.
