Microsoft have released a Windows Mobile 5 emulator that you can run on your pc, normally for developing software for the windows mobile. However, you can also use this to test and debug the setup of Direct Push with Microsoft Exchange 2003 service pack2. This is great to try before you blow up a users phone as you test stuff out. Seeing as though Direct Push has only just started being available on the phones, it is unrealistic to know how to get it working out of the box.
