hi! i bought an iPhone hardcover in an AT&T store, it's full hard cover in transparent plastic and i comes in 2 pieces (front & back), the gig is that it brings it's own integrated protective film in the front part of the case. The problem is when i put it together and touch the screen theres like bubbles with like an "oil in water" color, and it drives me crazy sometimes, how can I put it together so that it doesn't leave any bubbles?? I have iClean btw if dats any help. TY!!!!
