It doesn't but the MiFi wasn't readily available when this version of Sync first came out (late 2010), and it provided a "sales brochure tick point".
In addition, just about every smartphone these days can provide a hotspot.
Besides, with the kludgyness of My Ford Touch would you really want to depend on it for internet? (Given that the routing is a basic function in windows this feature probably performs pretty well even though nobody uses it! LOL)
