...Since creating a mobile cache requires "Mobile Data Access" capability and MSDs does not allow this capabilbity...
Hi Steve,
Have you submitted the obstacle you encountered with raster data not being extracted into the mobile cache when using MSDs on ArcGIS Beta Community website? If you haven't already, please submit a bug report under the ArcGIS for Windows Mobile Beta program so the Mobile Team can review and respond accordingly.
Thank you,
Denise
