Microsoft joined forces with Cingular, Orange, T-Mobile and Vodafone to announce the availability of the Messaging and Security Feature Pack (MSFP) for all their Windows Mobile 5.0 customers. The MSFP is the upgrade that enables true push email when coupled with a Microsoft Exchange Server running Service Pack 2 (SP2). This will no doubt give RIM a run for their money by competing with the BlackBerry service, assuming RIM is still around in a few weeks. A number of new MSFP compatible phones were also introduced in the announcement today. The full press release is on the Microsoft web site.
