Patch for Smartphone 2003 SDK Released
If you develop for Windows Mobile based Smartphones you'll be aware of the SPDPS utility. SPDPS is what you use to configure a Smartphone to allow you to deploy and debug on it.
A combination of the work in Windows XP SP2 and eMbedded Visual C++ 4.0 SP4 breaks the SPDPS utility in the Smartphone 2003 SDK. Never fear though, the Windows Mobile team is here to support you!
