I believe the only difference is it works on different bands.

I believe the only difference is it works on different bands.

for the most part, it's only the frequency

t637=850/1800/1900 (americas)
t630=900/1800/1900 (rest of earth)

I think I heard something about the t637 being capable of being upgraded to do gsm push to talk... but that dosen't seem to work on it at the moment

No PTT for the T637. The ONLY difference is the bands.

[Box215]

Ok, it supports it. But neither ATT or Cingular support PTT, so whats the difference?

[R@ziel]

not now, but perhaps they will someday! ;)

what mobile companies do support ppt, because there is some ppt phones out in england and if no network supports them i wont get one (obviously)

Orange released PTT (or P2T) it on their UK network this week, initially for corporate users (using the Treo 600) - but plan to roll it out to other user groups and devices in the future
