Thanks for the suggestion! However I already looked at that on Amazon and while the page states that the GLAS.tR Slim has "rounded edges" it also says this further down:
"• Glass sized smaller than iPhone 6 front panel
Due the iPhone 6 (4.7") having a curved display, the GLAS.tR Slim is shaped to fit the flat part of the display to prevent lifting at the edges."
So I think this means that those rounded edges still cut off before the curves of the screen but that the edges will not be sharp like when you simply cut glass. They soften the edges so they're not as noticeable, chip less easily and fit with more cases. Which in itself is a good idea.
I've been reading the reviews on this GLAS.tR product and it appears as though the bad reviews have all come from people who were disappointed that the screen protector didn't cover the curves, but the reviewers that choose to overlook this seem to like the product. I might have to try this one if the one I ordered does not satisfy. I'd rather have tempered glass if neither film nor glass will wrap completely around the curves and I'll just get a case that has a lip to protect the edges that the glass doesn't.
