Nah I've got an iPod Touch 32gb. Just got the v2.0 firmware on it for the apps store. The 3g iphone apparently has a faster gfx chip and main cpu so it'll be interesting to see how the games like Monkeyball run on mine which is the 1st gen of cpu and gfx chips.
Still it is a sexy beast. I have a love/hate relationship with it. One minute I want to chuck it on ebay and sell it, next minute (like the v2.0 upgrade!) I love it again.
