The most important of these is the inclusion of EDGE data services, a first for a Sony Ericsson handset. The Z500 includes Class 10 EDGE, offering speeds of up to 240 kbps.
The Z500 also includes a VGA digital camera for both still and video recording. Pictures can be displayed on the 16-bit TFT main display, while the external 4096-colour display can function as a viewfinder or display picture caller-ID when closed. The external screen can also be used to read text messages and perform other simple functions.
Features include a Wireless Village instant messaging client, MMS, e-mail support, a full organizer with sync ability, and push-to-talk over cellular (PoC). PoC allows functionality similar to walkie-talkies and is aimed at businesses and consumers alike. Media functionality includes a polyphonic ring-tone composer, 3D Java gaming and force-feedback.
