Nokia 6230

The Nokia 6230 is a mobile phone based on the Nokia Series 40 platform. It features a 16-bit TFT color screen with a resolution of 128×128 pixels, a VGA camera that can record video clips in H.263 (SubQCIF) format at 128×96 pixels, built-in Bluetooth wireless technology, FM radio (when a wired headset is attached to the Pop-Port interface to act as an antenna), and playback of MP3 and AAC audio. It is also EGPRS (EDGE) capable of speeds up to 220 kbit/s. In addition, it has changeable Xpress-on covers available for purchase.

It uses an Extended Li-Ion Battery of 850 mAh. The 6230 accepts MMC memory cards up to 1GB in capacity (supported by later firmware releases) on which multimedia files and data can be stored. SD cards are not supported. It operates on either GSM 900/1800/1900 MHz (Nokia 6230 RH-12), or GSM 850/1800/1900 MHz (Nokia 6230b RH-28) for the North American market.

Cingular Wireless was the primary GSM carrier that offered the Nokia 6230b in the United States. Other companies such as Cincinnati Bell, Simmetry Communications, Viaero Wireless and Telcel also offered this model.

Nokia 6230 was nicknamed Matrix during development. The updated version 6230i was nicknamed Matrix 2.

Nokia 6230i

In 2005 Nokia released an updated 6230i model (RM-72) which includes a 1.3 megapixel camera, 208×208 screen resolution, a slightly larger display, and a raised selection button in the midst of the scroll key. 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. In addition, the graphical user interface was overhauled, and many of the icons featured on the 6230i are the same as those now used uniformly across almost all new Nokia phones.

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.
