Identification and Background
The Sony Ericsson T68i is an update to the T68m model. It includes full MMS capability, a photo album capable of storing up to 200 pictures (does not have a built in camera), and compatibility with a camera accessory. It contains plenty of memory space, new games, sound browser, and more features. It was eventually replaced by the T100 model.
