Ok. When the iPhone comes out I plan on putting a protective film on the front and back along with a bumper. Tradionally I use Invisibeshield but thought I'd try something different. I have always had success with invisiblshield. My question is will the Ultra work with the bumper? I have no earthly idea what makes it an Ultra but speculate it's thicker than the regular. If this is the case is it so thick that the bumper will not be able to fit?
