I don’t think SavaJe should be in the Linux category. I do not recall SavaJe is related to Linux. At least all the marketing effort of SavaJe was that it is a Java-based platform. Initially it was not Java ME (neither MIDP nor PP) but Java SE, and that is where the company name is coming from (SavaJe -> JavaSe).
Linux in the mobile world apparently is very diversified. The most successful Linux mobile phone manufacturer is Motorola. It has launched many devices in Asian market, including ROKR E6, a ultra thin phone with 2 MP camera and touchscreen. Other major manufacturers include E28, Haier, Lenovo, NEC, Panasonic and Samsung. Mobile Linux vendors include ACCESS, MIZI, MontaVista, Trolltech and more.
Some other recent news about smart phone OS:
Windows Mobile Pocket PC/Smartphone will be renamed to Windows Mobile Professional Edition and Standard Edition.
ACCESS renamed Palm OS to Garnet OS.
Berry 411 (for Blackberry) gives you instant access to yellow pages, white pages, Google, movie times, weather, encyclopedia, and Froogle results. You can dial any phone number directly from the display or add it to your phone book. The results are formatted to fit the Blackberry screen, and search completion saves typing.
You can create new clients for Berry 411 backend.
