Finally after waiting for the release, pre ordering it back in June, it came today. It's awesome, top quality from power support as usual. Went on perfect, no bubbles and with my Belkin grip vue and Zagg custom skin on the back, I'm good to go.
Got my combo set (front and back) from power support in today as well. Fast shipping, ordered Wednesday before midnight got it this afternoon.
The back was extremely easy to put on. No problems what so ever.
The front though, just a little bubble around the home button that I can't get rid of... Tiny bubble. Did the whole scotch tape method several times. First time that ever happened to me and I've used powersupport on my 2G, 3GS and iPad. But it doesn't bother me. I now feel at ease knowing that the front and back glass of my iPhone 4 will be safe from scratches.
The quality for the combo set doesn't feel the same compared to the previous generations models for the 2G and 3GS. Feels a bit more cheap build, if that makes sense.
Overall I'm happy and will continue to support this company as I have always been.
