Sony Ericsson today announced the Z525, an update to their Z520 clamshell GSM phone that adds Push-To-Talk (PTT). The Z525 is otherwise identical to the Z520. Although Sony Ericsson did not announce the type of PTT technology in the Z525, the Z520 is currently offered by Cingular where it has sold very well. Cingular uses Kodiak's RTX PTT technology, and Sony Ericsson did license Kodiak's PTT technology in August of last year. The Z525 is expected to hit shelves in the second quarter.
