I suspect that the sheer nervousness and exhilaration associated with getting a 3G iPhone has caused your hands to swell up, making the device appear smaller.
i actually suspect the hype has made you think your getting a compleltly new item when in reality it is not that much different. Hope the come down or as we call it buyer remoarse does'nt kick in yet.😉
The phone IS wider. It now matches the sizes of the ipod touch. The original iphone was not as wide and a bit taller than the touch. The screen is exact same size, the actual casing is wider.
