JH3,
I've tried several different screen protectors:
1.Apple and ATT Stores sell a simple peel and stick on. I used one on my first generation Iphone and it worked fine. The have a glossy and antiglare.
2.Best Skins Ever (online) is priced nicely. I used it on my ex-Bold and found it pretty simple to apply but does have the orange peel effect.
3.I have the Invisible Shield on my present Iphone, costly, and tricky to apply. I am so finicky about not seeing bubbles that I wasted money until I got the darn thing on perfectly. BUT, having said that, I am happy with it. One does not see the peel effect when looking at a page on the screen and I feel I see less smudgy, messy fingerprints with it.
Do a search here on 'screen protectors' and you will find tons of posts and opinions.
Good luck with your choice.
