In security circles, the talk on mobile centers around mobile management, protecting access to and use of corporate information by smartphone users. This summer's iOS 4 has been a game-changer for most IT organizations, giving the Apple iPhone, iPad, and iPod Touch security capabilities equivalent to those of Windows Mobile and meeting the needs of most BlackBerry users, ending the main objection at many companies for allowing iOS devices in. (When used with BlackBerry Enterprise Server, the RIM device does remain more secure for high-requirements organizations.)
