“This is one more step in delivering webOS to all developers and providing the tools they need to build great applications for Palm phones,” Chuq Von Rospach, Palm’s Developer Community Manager, said in a blog post.

Meanwhile, Motion Apps has announced that its Classic Palm OS emulator for webOS devices will soon be able to run HotSync.
