- 960 x 640 pixel screen, that's 2 x current and means existing apps scale easily
- 8MP rear camera
- front facing camera for 3G video calling and IP video, e.g. iChat, Skype etc.
- Video recording in at least 720p and import into iMovie.
All in all - worth waiting for if it lives up to this.
WRT the 900 3G - I think unlikely, say 75/25 against. However the new Nokia N8 does have 850 and 900 3G support - scroll down to 'Operating Frequency' section. Every other handset is producing 2 x 3G variants.
