If you use an AirTunes network (that’s the unwired version of iTunes done through an Airport Express - click here for more), you can use your iPhone or iPod Touch as a remote control instead of running through the house to change your iTunes settings.

This is possible by a piece of shareware called Signal from Alleysoft, which basically enables your wified new thingamabob as a remote control. Signal has versions for Phones/Touches and Pocket PCs and costs US$24.95. The downloadable trial is full-featured and has no time limits, but displays registration reminders for a third of your content until you up and pay.

Signal lets you:

Play, pause, and stop your music
Move between songs in the playlist
Adjust the volume
Rate songs
See the current album art
Browse and search your media library
Add songs to the queue
Remove songs from the queue

Apple’s released Apple Base Station Extreme firmware update Version 7.2.1, which certifies the base station for the IEEE 802.11n Draft 2 specification. In their usual considerate and detailed explanation of what they’ve done, Apple says:

This update also includes bug fixes and security updates.

It requires that you have Airport Utility 5.1 or later, and, of course, a Base Station Extreme with 802.11n. Get the firmware update here.
