The Sony Ericsson Z series phones might soon bid adieu if rumors are to be believed. We will most probably see a new device as a perfect replacement for Z750 (Sony Ericsson’s first tri-band HSDPA and quad-band EDGE enabled phone supporting Java Platform - the T767, as Xell from Esato board has it. It comes packed with a 3.2-megapixel auto focus camera, HSDPA, GPS, 2.2-inch QVGA display and LED signal strip. Although now it is still in the concept stage.
