A new hack by a Chinese manufacturer will allow you to make your iPhone 4/4S’s Apple logo glow. Much like the MacBook’s, the logo will glow once you turn the device on. K.O. Gadget, the maker of this mod, says it can be done at home in less than five minutes. For $42, K.O. Gadget will send you the kit to perform this hack, and obviously it would void your iPhone’s warranty.
