Microsoft takes big step in managing enterprise handhelds.

"[Microsoft] also said that a handful of mobile carriers are preparing subscription service plans for enterprise customers, built around MDM. The carriers will offer simplified licensing for the application, one-call tech support, and an optimized network connection for subscriber devices... The new mobile operator services being built around MDM are due out later this year from various cellular carriers, including in the U.S., AT&T and Verizon Wireless. According to Traynor, the implementations of these 'Mobile Services Plans' will simplify mobile deployments by giving enterprises a single locus for MDM client licensing, device purchase, support and maintenance, and a guarantee of a high-quality network connection for mobile users."
