Pocket PC Phone with PTT (push to talk) button

[ALBERTO]

Will there ever be a Pocket PC Phone with PTT (push to talk) button so it can be used as a radio as well. Some GSM carriers are offering this service to get rid of NEXTEL. I think this phone should be there by now. i found one by Samsung the MITs400 but is for Korea and CDMA not GSM, do you guys know better?

Best,
ALBERTO
