Well, the iPhone is quite a phenomena, and it's being talked about alot, so I think this is the right spot for this thread.
To be honest, I've never heard of the Samsung Tocco, but I hear the iPhone G3 is very good IF you have the money. It's definately going to cost you alot because of the internet, email, and everything else it has.
Iphone 3G will always be better. It is a great phone and it is all AT&T seems to have that keeps people buying from them. My friend told me he only switched to AT&T for the phone.
