Doug wrote an article about Colorware, a company that will permanently color your iPhone, not too long ago. However, at the time, the process was not yet available for the iPhone 3G. Well, it is now available! Below is a break-down of the color options, price and an example screenshot.
Back – $150
Frame – $20
Button – $20
SIM Card Tray – $10 (this is a new option)
Earbuds – $10
iPhone Dock – $20
You do not have the option to choose a color for the bottom half of the back of the iPhone 3G (obviously) but, you also do not have the option to choose a color for the Logo on the back of the iPhone 3G…both of which were available with the first gen iPhone. I’m not sure why you can not color the Apple Logo like you could with the first gen. It is too bad because that is the part that has the most scratches on my iPhone 3G!
