According to news out of the European Developer conference, PalmSource plans to continue to develop Palm OS 5, even after OS 6 is finished. The company will release a special version of OS 5 that will target mobile phones.
PalmSource just announced that the next generation Palm OS 6 will be complete on December 29th. Palm OS 6 will be aimed at high end converged devices and traditional handhelds.
According to a report in the Computer Business Review, PalmSource will continue to develop OS 5 and will create a special telephony version of OS 5 aimed at low-end "feature phones." PalmSource president and CEO David Nagel told journalists at the company's European developer conference in Munich, Germany yesterday that the maturity of OS 5 will make it ideal for use on mass-market handsets.
The version will be aimed at Smartphones and other low-end "feature phones." PalmSource feels that the small and compact footprint for OS 5 makes it the ideal choice for these types of devices and will bring lower price points and higher volume. PalmSource has not announced a time frame, but it is expected sometime next year.
The report also uncovers that, PalmSource will release a software development kit for OS 6 at its spring conference on February 10 next year.
Da ich gerade sehr enthusiastisch bin, prophezeie ich schon einmal, das Symbian und Windows for Smartphones eine schwere Zeit bevorsteht! 
Freude! Freude! :p
