Ok, my white iphone 3g has been covered in ZAGG invisible shields since I first bought it (over a year ago). With that said, let me tell you the fate of the three IS's that have come and gone thus far: IS #1 -- improperly installed, due to my own inexperience with the product and began to peel back along the edges. I didn't buy the IS through ZAGG (used bestbuy instead) and therefore did not have the lifetime warranty because I lost my receipt IS #2 -- installed properly and was very happy with the product until about 3 months into I noticed that the IS began to become discolored and turned a mixture between yellow and blue (Actually a puke color). I had gotten this IS as a gift and therefore did not have the receipt, so I finally decided that I'm going to buy a third IS and this time I was going to keep the receipt and register the product. IS #3 -- I've now had this IS on for about three months and I am extremely happy with the purchase and would/do recommend the product to all of my friends (actually even bought a fourth IS for my girlfriend) BUT I am seeing the discoloration again. PLEASE, somebody tell me how to get rid of this or if the warranty covers this horrible flaw in the plastic turning puke colored. I just figure at this point that I have spent over $100.00 on invisible shields and I really don't want to spend any more. I will try to get a quick picture of the back my phone to show you guys how disgusting it is.
