I use Invisible Shield for my Curve 8310. I am very satisfied with it. Does what it is supposed to. A little pricey, but i am picky about screen protection, so money is not the concern for that. I will say this though, I have NO patience when it comes to applying these things, so when I bought my Curve last week, I had the kids at best buy install this screen shield, and I must say the little guy did a really good job...i was impressed! It looks really good and you really can't notice it's on there..good luck hunting!
