Microsoft has posted on one of its developer web sites the Software Development Kit (SDK) for Windows Mobile 2003 for Smartphones. This gives the world its first detailed information on this upcoming operating system for smart phones.
One of Microsoft’s goals for this year to was to unify as much as possible the code base for its operating systems for handhelds and smart phones. In June it released Windows Mobile 2003 for Pocket PC and it will soon release Windows Mobile 2003 for Smartphones. Both of these are based on Windows CE 4.2 .NET.
The upcoming version of this operating system changes the way email accounts are handled. Messages received from each account are kept separate, and when starting a new message the user is given the option of which account to send it from.
The .NET Compact Framework is included in the Smartphone 2003 ROM. This is a subset of the .NET Framework that provides much of the functionality in a smaller footprint.
These are just some of the most significant changes; there are numerous other smaller ones.
The first handsets running Windows Mobile 2003 for Smartphones are expected in Europe later this year. They should be available in the U.S. early next year.
