So there is a new company I just found. They have a mod that makes the Apple Logo on the back of the iPhone 4 and 4s light up, like on the macbooks. I was wondering if anyone knows a little more about the process. I know they install a small LED bulb. Its a really neat look and I would love to install it on my phone, but they are based in the UK and I am in the USA, so it would be really expensive.
