If you use Virtual Earth Mobile, you will need to update your app to version 1.50 before February 12.  That's the day that the Virtual Earth servers will switch over completely to their new interface, and old clients will stop working.  The new version is attached to this blog entry.

In addition to supporting the new interface, new features include:

• driving directions from the MSN Mobile website
• WiFi locator
• asynchronous loading of maps
• stretching map tiles that are already downloaded until new tiles are downloaded
• finer zoom levels
• help page
• support for builtin GPS on the HP iPaq

Thank you.
