TrustedReviews posted a review of the Nokia N90 3G Handset

The N90 is a tri-band GSM and 3G handset, but its 3G capability is not the headline feature. That accolade goes to the same feature that accounts for the N90’s size - the camera lens. Nokia proudly announced at launch that the N90 would feature digital optics courtesy of Carl Zeiss, including autofocus, 20x digital zoom, and two megapixel image capture, as well as a macro mode for close-up shots.
