Applications can be developed for windows mobile 5.0 with Visual Studio 2003 / eVC++4.0 ( free ) / Visual Studio 2005
To test the application there is something called Windows Mobile 5 emulator where the program can be tested.
Here you can find a application to enquire about available bluetooth devices : http://www.pocketpcdn.com/forum/viewtopic.php?t=7800 runs with eVC4.0 and Pocket PC 2003 SDk
There are some sample applications at http://www.broadcom.com/products/bluetooth_sdk.php which also require Pocket PC 2003 SDK for testing.

Appln dev for Windows Mobile 5.0 (OS) can be done with VS.NET 2005
Appln dev for Win CE 4.2 (OS) can be done with eVC++4.0 ( with service pack 4 ) and SDK from Win CE
Appln dev for Pocket PC 2003 can also be done with VS.NET 2003 ( Visual C# only ie managed code )
Appln dev for Pocket PC 2003 can be done with eVC++ 4.0 ( C++ unmanaged code )
SDK avaialable for Win CE 5.0 should be used for appln development for Win CE 5.0 based devices ( STANDARD_SDK,Windows CE .NET Utilities v1.1 for Visual Studio .NET 2003)
SDK avaialable for Win CE 4.2 should be used for appln development for Win CE 4.2 based devices
eVC++ 4.0 - Windows Mobile 2003
eVC++3.0 - Pocket PC 2000, Pocket PC 2002, and Smartphone 2002
eVC++2.0 - Microsoft Windows CE version 2.11 and version 3.0 if the correct SDK is installed
eVB - Windows Mobile 2002-based Smartphone or Windows Mobile 5.0-based devices
Win CE 4.2 and below, you will still have to use VS.NET (2003). And there will be no support in VC++ 2005 for CE4.2
