It sure took 'em long enough but Apple finally got right with the
Lord WWAN. The latest software update brings official Novatel ExpressCard and USB modem driver support (like the XU870 HSDPA card pictured) for HSDPA and EV-DO cards. The drivers work with the latest intel-based MacBook and MacBook Pros on Cingular, Sprint, and Verizon Wireless networks. Just give your Software Update a nudge and say goodbye to those suspect driver hacks you've downloaded from the forums.
P.S. -And yes, for those paying close attention there's an unannounced Verizon Rev. A ExpressCard, the V740.
