In early 2005 Nokia released an updated 6230i model (RM-72) which includes a 1.3-megapixel camera instead of a 0.3, 208×208 screen resolution (65,536 colours), a slightly larger display, a raised selection button in the midst of the scroll key, and a modern redesigned menu.
It is also standard UMS (USB mass storage device class) compliant, i.e. no proprietary drivers are required to transfer data to and from the device’s memory card. It weighs 99 g (including battery BL-5C) and the dimensions are 103 mm x 44 mm x 20 mm, 76 cc.
The BL-5C battery that comes standard with it will last about 150–300 hours, depending on usage.
This model was available only in GSM 900/1800/1900 MHz; Nokia did not release an 850 MHz version for the North American market.
The next model in the 623x series is the 3G GSM/WCDMA Nokia 6233.
