Just thought of something else...
Thinking about buying an iPod Nano for $49, selling it on ebay or craigslist at near full price and using the money from that to get one of those custom paint jobs from Colorware for my iPhone. I'm really a fan of the blue / yellow / black version on their homepage. Or maybe one with different gunmetal metallic type finishes. I'd also really love to have an iPhone where the Apple logo on the back glowed. How hard do you think that would be to rig up?? What about a transparent case?
