So I still have my iPhone 4 with an old 3G case that it fits into perfectly. It is still 'naked' though in terms of screen and back protectors. After much research it looks like the Power Support Crystal Film has gotten the best reviews for the iPhone 3G and 3GS. Im going to make the plunge but am undecided if I should get the regular or the 'HD Antiglare'. Any help or insight will be appreciated.
