I was at wallmart today, some guy was on his iphone 4 with a blue lit up apple logo. At first i thought it was just a black case with a blue logo, but as I got closer, he was not using a case at all, and the apple logo was actually glowing blue.
I know the first gen iPhone's can do this and after all, it is easy to take off the back cover of the ip4. But i thought i had to share this cause its the first ip4 i ever seen with this mod.
I saw a guy with a multiple light logo...i.e...went from red to blue to white. Thought it was cool, heard him mention that his wife's company did the mod/software.
Not sure if it is on Cydia tho, but cool none the less...
