32 days to freedom! lol i am currently right there with you big9erfan! august 1st, i get to leave Verizon for iPhone 3GS bliss
as for a screen protector, it seems many of the 3GS users are opting NOT to apply one. guessing here, but the iPhone glass seems pretty resistant to scratches. now with the oleo coating, it is now resistant to smudges & fingerprints too. i may try skipping on the purchase of a screen protector and just going with a case protecting the backside.
either way you go, good luck and enjoy the phone! if you find a great case/protector, be sure to let us know!
