It's not exactly revolutionary update, but if push-to-talk functionality was all that was holding you back from Sony Ericsson's semi-low-end Z520a, the Z525a should fit the bill exactly. The new model adds a PTT button -- well, more like, repurposes the camera button for PTT -- and nothing else. We're sure this will keep the Z520a purists happy, but we could've done with a bit of EDGE data or an improvement upon the VGA camera and 160 x 128 pixel display. Oh well, at least now we'll be able to complain in short annoying bursts.
