PalmSource said it has reached an agreement with Qualphone to incorporate the latter’s push-to-talk-over-cellular client to the Palm OS operating system for mobile information devices. The collaboration is designed to provide users with an easy-to-use and reliable push-to-talk experience on Palm Powered phones and mobile devices, PalmSource said.

Qualphone's PoC client is certified to meet the end-to-end interoperability standards of Nokia's back-end infrastructure, enabling PalmSource to leverage mobile operator networks worldwide that have standardized their mobile services offerings based on Qualphone's technology, the company said.
