PalmSource has announced it is to focus more on devices that handle both voice and data communications.
PalmSource chief executive Dave Nagel told Associated Press: "We've been a player in this space for a long time, and we're making it official now that it's a key market for us. We're going to go after it with every weapon that we have."
The new operating-system strategy is designed to get the Palm OS included on more mobile phones, including lower-priced models. It will now simultaneously develop multiple versions of its OS to be aimed at different parts of the mobile phone market.
PalmSource calls this a: "Dual-version strategy." For example, it will develop a new operating system aimed for the smartphone market while keeping the older Palm operating system – previously known as Palm OS 5 but now renamed Palm Garnet – available for other gadgets.
Nagel said: "Two versions of the same platform will allow us to go after a broader swathe of the market than we could do with either alone."
Palm's newest operating system, Cobalt, already includes functions for multitasking and security, but will soon include telephone features, according to Nagel.
