The portal includes an online calendar, address book and invitation service. By downloading an application to their handheld devices, Palm owners with wireless access can also use MyPalm to view Web pages, share calendars and download software.
MyPalm is a revamped version of the Palm.net portal. The free service builds on the Web-based calendar that Palm picked up when it acquired Anyday.com earlier this year.
Palm representatives did not immediately respond to calls seeking comment.
Santa Clara, Calif.-based Palm, which depends heavily on the sale of devices for its overall revenue, is trying to diversify by licensing its operating system and providing Internet access and online services. These categories currently account for 3 percent of the company's revenue.
As part of the new service, Palm owners will be able to share their calendars. Last week, Palm announced that it acquired Portland, Ore.-based WeSync, which makes calendar-sharing software.
The wireless features of MyPalm are primarily aimed at Palm VII owners. However, last month Palm started shipping a $40 kit that allows owners of its Palm III, Palm V and m100 handhelds to connect to the Internet via a mobile phone. Some, but not all, of MyPalm's features are available to owners using those models and the wireless kit.
