"Microsoft does not mention direct support of non-Windows handheld devices, but it has formed a partnership with mobile services company Enterprise Mobile Inc., out of Watertown, Mass., which offers integration services between the Windows Mobile OS and other platforms.
Symantec Inc. (Altiris), LANDesk and Novell Inc.'s mobile management products support Windows Mobile, Palm OS and RIM's BlackBerry. No vendor has the ability to support Apple Inc. iPhones, which are going to grow in popularity in enterprises, Mann said.
There is also Sybase Inc.'s suite that supports Windows Mobile, Palm OS, Symbian, but not BlackBerry, and Computer Associates that solely supports BlackBerry.
IT shops do not have much choice in device selection at this point, however. For the most part right now, the choice is up to employees, with IT left to figure out how to support iPhones, Windows devices, BlackBerrys, Palms and others."
