Good news. I sent an inquiry to the nice folks at boxwave.com asking them to
add a 770 screen protector to their lineup. Their first response was to use their
universal protector and cut it myself. ( which I'm far too inept to do )

BUT, I just received another message from them saying that they added a 770 screen protector to their lineup. ( actually they added two models - one anti-glare and one crystal clear )

ClearTouch Crystal Protector

Anti-Glare

I've had really good luck with one of their protectors on my palm one lifedrive. It was easy to apply and looked great. Hopefully the 770 protector will work as well.
