powersupport crystal lcd - how much coverage?

hi folks,

just wondering how much of the lcd screen the power support crystal film protects.

does it go edge to edge right up to the chrome bezel??

the reason i ask is that i bought a few off ebay a while back. i finally got my iphone yesterday and installed them, but they dont seem to cover the lcd edge to edge...

also, the cutout for the earpiece and home button are not perfect.
i've got the screen aligned with the home button, but the earpiece area is totally off!

just wondering if this is an older version of the crystal screen or something?? (since i bought it off ebay many months ago).

any help would be appreciated!
thanks,
steve.

i just checked the box and it seems like this protector is for the original iphone...whereas i have the 3gs.

i didnt think there was much of a difference in terms of screen and earpiece/home button location between iphone and iphone 3g/3gs...
