Yes but the only differences are that its faster has Siri and has higher mega pixel camera also the screen is brighter and looks nicer.
The IPhone 4's from Verizon are the same as the IPhone 4's from AT&T. The only difference is the service.
Yes, you can get an iPhone 4 with 16GB. The iPhone 4 comes in three different GB capacities: 8GB, 16GB, and 32GB.
they are different in size and shape, can't you replace iPhone 2G case with iPhone 4 case.

The difference you will see between the iphone 3G/3G S and the iPhone 4 is quite noticable. Especially the design. AS for the iphone 3G,there is no recently used apps bar (multi-tasking), you can't have a background wallpaper on the homescreen. As for the 3G S, you have both of these features. However, the iphone 4 has the Retina display, which the previous models do not. The iphone 4 has facetime (video calling), which the previous model does not. The iphone 4 can do HD video recording, has 5.0 MP with flash. I believe the 3G does 2.0? and the 3G S has 3.0 MP to it. No flash on previous models. Really, you can just go to the iphone section and i'm sure you can compare between the iphone 4 and the 3G S. In US, they do still sell the 3G S model but in 8 GB of storage, each country could be different where they could still sell the 16 GB model or the 32 GB, but very unlikely, unless they have few in stock. iphone 4 comes with either 16 GB or a 32 GB.
Sadly, no. It has to be on.
Not really as there is differences in the operating software and different hardware on bother versions of the iPhone.
No as the the shell (body) of the phones are different
No as the handsets are different shapes and size.
