I agree they don't look good but I put one on my 2g iphone the day I got it and was able to sell the phone 1 year later 4 the same price I paid 4 it becasue it was perfect- since I been usuing the LV case on my new 3g 2 weeks old the phone has 2 chips in it(the black/white backs chip fairly easily) becasue of small bumps with no protection on it so I am going to buy one just to keep my phone in good condition so I can keep upgrading as the new editions come out.
if the back of my phone starts to crack, i'll return the phone. the 3g backing have had issues w/ cracking and people have returned them for new ones. you came out w/ a good deal if/since you can sell the phone for the same price!!!
in regards to anti-glare film...i got it from the apple store. they are specifically for the 3g iphone so make sure you get it for the right application and not for the non-3g models because the sizing are different.
