I see it's been a year and this issue is still not resolved. There is still no version of the MobileCache2Shpefile tool for ArcGIS 10.1, the 10.0 version still doesn't run in Window 7 64-bit, and if you mess up your checksum by making any change to your MXD file, there is still no alternative for getting the data out of your cache. Oh, and I just love how the Syncronize Mobile Cache tool in the Mobile Toolbox always says it is successful, even when it doesn't work. I was lucky - only 4 points to re-create, and I could use the mobile app to get the coordinates of them, but I'm a little disappointed that this major, critical issue has not been addressed in a year.
Get your act together ESRI, your competitors are starting to nip at your heels, and every unfixed issue is just one more reason for people to leave you for someone else.
