iphone covers

Can I use same covers on iPhone 2G and 3G?

Hi, I have iPhone 2G and I want to buy some cheap cover (on e-auction). Unfortunately, mass of the nice covers have headlines like “Cover for 3G…”. I know, that 2G and 3G have different dimensions, but just only a little.
Does anybody have tried it?

i dont really see a difference between them so yeah go for it ders nothing you got to lose.

help? http://answers.yahoo.com/question/index;_ylt=Ahl8sN3Vfllv9Wiy4.RbPtDsy6IX;_ylv=3?qid=20090812022209AAh6lvN
