I just put on one of Xtremeguards newer dry install protectors. It goes edge to edge but doesn't stay stuck down on the curved part. I put it on last night and after about the 4th time taking my phone out of my pocket this morning it caught and peeled off. I also got their wet install version, which I'll be putting on tonight and I'm sure will stick better, but I don't like the texture of those so I'll only be using it until I get a better dry one.
If you don't mind the more rubbery wet install protectors, that's your best bet for edge to edge, otherwise the smoother plastic ones have to be cut short for a reason.
