Three closely related handsets running the Symbian Series 60 operating system, the Nokia 6680, 6681 and 6682 feature Bluetooth, a 1.3 megapixel camera, removable memory on hot swappable Dual Voltage Reduced Size MMC (DV-RS-MMC) cards, stereo audio playback and a large 176x208 18-bit (262,144) color display. The Nokia 6680 replaces the Nokia 6630, the 6681 replaces the 6600, and the 6682 replaces the 6620. Announced in February 2005, they reached the market in May 2005.
The primary difference between the 6680 and 6681 in technology terms is that the 6680 is a 3G device with a secondary camera on the front for video calls, and the 6681 is aimed at markets using the EDGE data standard. Significantly, the Nokia 6680 is the first Nokia phone to offer full built-in video calling capabilities, which should help with its acceptance by 3G operators. The 6630 also supported video calls, but did not have a camera on the front.
Both phones operate on GSM 900/1800/1900, with the 6680 operating additionally on UMTS 2100.
The Nokia 6682 is a variant of the 6681 designed for US markets, using GSM 850/1800/1900.
