Read an article about Nokia updating their firmware overseas to alter some of their existing phone models to have PTT so this may become available for the 6255 (If we get it that is). Just take the phone available for the update the your provider and its done free. So I may be proved wrong when I said the only thing the Nokia 6255 doesn't have is PTT although the 6255 wasn't on the list in the article. Still Fingers crossed!
