That's not the only new feature, other key ones include:
- Voice control- enabling you to use the ipod functions as well as others with your voice.
- Compass- a built in compass aiding the maps feature.
- Copy & Paste- works like a computer to cut copy and paste from the web etc.
- Much faster processing- somehow they've managed to make just about everything in the phone faster (including the web and apps).
- Search- searches across all the content on the phone and email server.
- MMS- extended multimedia messaging support.
- 3mp camera for stills- I know it's still not much compared to some of the 8mp heavyweights but still an improvement. It also has autofocus and manual focus (by tapping the area you want to focus on).
