Hello, I'm looking for designing a software for the iPod Touch but I don't find the exact dimension and resolution for each visual element likes icons, buttons and backgrounds. What's the resolution: 72 ppi, 163 ppi (like the spec of the iPhone and the Touch) or 300 ppi? How do I get a software in my iPod Touch, like Weather, to see the code behind? I used iShare IT to transfer the Weather application of my Touch but it seem corrupted. Thanks for your help.
