Basically PET is PET, the difference is, how it's packaged and cut. I ordered one off eBay (screenguard brand) and it is fine but doesn't lie down properly around the earpiece or home button. Now, assume I won't spend the better part of $20 for a small ag screen...anyone know of a reputable site for unbranded or generically branded PET screens that work? Mono price any good for 'em? I already get cables etc three, but never tried their ag screen...though a review said it didn't stick correctly around the edges. Alternately, any tips for getting the trouble spots to stay down? Is not dust..just..doesn't stay. Thanks all! I'm trying to find alternatives to the third party companies rebranding inexpensive stuff and marking it up 500%.
