It's a 3G im Upgrading from. It is alot louder and the vibrate is stronger too in my opinion.
The regular speaker crackles too. This is terrible IMO.
Had to turn volume to 50%, I kept jumping when I get a text it's so loud. Always had it on max with my 2g.
Its more like iPhone 2g. Then iPhone 2g 2.0 if you want to measure it by the hardware. The only hardware that really changed from 2g to 3g was the 3g receiver.That's my take on it. You had the 2g. Then you had the 3g.
This iPhone has many of the same parts, some internals improved obviously. But it's not only the software that makes it better either. If that was the case, the 3G and 3GS would be closer.
As you can tell from folks, there's an overall feeling of improvement across the board beyond the itemized refinements.
So I called it 3G 2.0 for those reasons.
