The amount of memory measured in megabytes installed in the system's hardware

MegaPixels: The number (in millions) of light-sensitive picture elements, or pixels, actually used by the camera's image sensor (CCD) to record light, and which are reflected to the final number of recorded pixels stored on the memory card.

Polyphonic ringing tones are played through a speaker rather than an ordinary buzzer, which means that you get vastly improved sound quality for melodious ringing tones, message alerts, and gaming sounds.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

General Packet Radio Service is a wireless data transmission service based on packet transmission. For example, if an email is sent by GPRS it will be reduced into .packets. of information. Each individual packet travels to its destination by the quickest possible route. This means the different packets from the same mail can travel separately through foreign networks around the globe in order to avoid obstructions. At the pre-set destination they are rebuilt and presented to the recipient as a whole. GPRS offers instant access, and permanent connection between the mobile device and the network. With GPRS you only pay for information sent or received, rather than for connection time.
