Keeping an eye on the exchange team blog, Max Ciccotosto pointed out that Dataviz has released Roadsync. This means java, palm and Symbian based devices now can sync directly to Exchange Server Activesync infrastructure. The list of fully supported devices on the Dataviz site are here.
Dataviz state that they will update their product to work with Exchange SP2, but I assume this will not include support for security policy enforcement provided by the feature pack.
