MMS

The MMS specification allows for the creation of messages sent from one mobile phone to another that can contain text, pictures, audio, and video that can be optionally organized into slides in a presentation. Unlike SMS and EMS, the MMS system relies on 2.5G, or newer, data connectivity technologies such as GPRS and 1xRTT. As such, the configuration required for its use is often far more complicated than that of SMS. CDMA based networks and devices, such as those offered by Verizon Wireless and Sprint in the USA, generally do not support the full gamut of MMS functionality, and often offer what is simply called Picture Messaging. Such services typically function similar to email in that pictures and videos are merely attached to a text based message instead of integrated into a full presentation.

S80

S80, previously known as Series 80, is the software platform that Nokia runs on top of the Symbian OS for its 9000 series of communicator devices. Nokia has announced that S80's functionality will be folded into the S60 platform, and that S80 will cease to be developed.

Nokia

Based in Espoo, Finland, Nokia is the world's largest manufacturer of mobile phones. Nokia focuses on UMTS and GSM handsets and produces relatively few CDMA handsets. At one time the company had agreed to spin off its CDMA business into a joint venture with Japan's Sanyo, a major manufacturer of CDMA handsets, in order to strengthen its position in the North American market. That deal eventually fell through. Currently Nokia rebadges some phone models produced by Korea's Pantech as Nokia devices for Verizon Wireless in the United States.
