Just received one of the second ones (properly shaped for SFII screen), but completely failed to apply it properly and ended up with loads of tiny bubbles under it. Its only a two stage application, not a three stage one. I tried to re-apply it a few times, then gave up and threw it in the bin.
The first sort are much easier to apply and are a tiny bit thicker too for added protection. They only cover the actual screen bit of the phone but are much better than the second sort IMHO.
