Can anyone tell me what the differences are between the iphone 2G, 3G and 4G? Obviously the 2G is older, but is there any actual difference?
I've got an itouch 3G at the mo, and would quite like to get the iphone. Wanted to get the other half one as well, so am going to have to look at older one's to be able to afford both.
Any info would be appreciated.
