Normally, a firmware release wouldn’t warrant a post on here, but this case is a little different.  Earlier this week, Apple introduced newer models of the Airport Extreme broadband router/switch and the backup appliance version, Time Capsule.  Along with that announcement came several enhancements that most figured would be released for previous hardware.  These features are enabled in firmware release 7.4.1. Â
While I’m not sure the firmware brings the dual band features to the older hardware The update does not include the guest networking or dual-band simultaneous networking, but the MobileMe integration (Back to My Mac) is included for older hardware (like mine).  This allows you secure access to your shared disks from far far away.  I installed the firmware last night and setup MobileMe integration.  Broke out the Mac here at work and whala, its working to home…  Now that’s cool.  I knew technically that it wouldn’t be a stretch for them to extend the BtMM functionality.
