This is the Invisible Skin for the T-Mobile G1. The same brand that developed the famous non-bulky skin for iPhone has now created the same high quality product to the G1. This skin will surely protect your G1 from scratches on its body and screen. This thin g1 skin improves the grip you have on the G1, and decreases your chances of dropping your cool phone 😉 . As the name says, this skin is almost invisible, adding just brightness/light reflection to your G1 phone.
