I'm easy. Just give me:

1. voice dialing through bluetooth headset (no need to touch the phone)

2. a really great PIM with tasks/to do that enables multiple contexts for each task, sorting by date of entry/deadline, search function + has an app for both the phone and the pc or even in the cloud so that all data backed up.

3. Real sat nav.

4. I forgot - paint that chrome bezel around the camera.

All other upgrades are nice to have, but not essential to me.
