Information Rights Management Activation for Windows Mobile 6: Part I 1/2

I just read on good authority that Microsoft will soon release an updated version (6.1) of Device Manager for Vista over the next few weeks. As soon as I see this pop up on the ‘ol RSS feed, I’ll be testing this out.
For kicks, I thought I’d post the machine certificate that is created on the Windows Mobile 6 device.

So you can see that the Windows Mobile 6 device does most of the work itself. My sense is Active Sync / Device Manager is needed to perform the authenticated connection to the RMS server to get the GIC. Anyhow, stay tuned and I’ll go through the process in more detail…once I get it working on Vista.
