If anyone had already attempted this with their iPhone 3G and found that the insides coming through on a transparent outside simply made their phones look ugly, then you will be happy to find out the innards of the iPhone 4 are not so bad looking. In fact, it looks slightly better to techy people when it is transparent. This modification can also be done fairly easily. The modification would require you to simply remove the glass covering and then apply paint thinner to remove the paint. Then you will have a transparent casing on your iPhone 4. This is a must for anyone whom enjoys seeing the inner workings of their device, plus it gives your iPhone 4 that unique feel, which will help ease the lingering idea that everybody else’s iPhone 4 looks like yours.
