When the second generation of iPod touch was announced, one slide on the presentation included built-in support for the Nike+iPod sensor. The cool thing was that you no longer needed the unsightly dongle hanging off your device. The touch just "sees" the Nike sensor and you could add it to the device quite easily. Plus, the app looked great on the bigger screen of the touch, and allowed you to multitask -- not that you should play Dizzy Bee while jogging, OK?

I hadn't thought about it until I got my phone home, but the sensor works just fine with the 3GS. As expected, the app is identical to that on the touch, although Apple posted a tech note regarding answering calls while using the Nike app, something you don't worry about on the touch. If you've never tried using the Nike sensor with either a touch or the iPhone, read on. Oh, and I don't have a Nike remote watch doohickey, but apparently those will work on the 3GS as well. If the Nike thing isn't your bag, we ran down some competitors a while ago.

To pair the device, go to Settings > (in App-specific settings) Nike+iPod and flip the switch to ON. At the bottom (you can see in our gallery) choose either Sensor or Remote, depending on what you've got, and you'll be prompted to move around (sensor) or press a button (remote). That's all there is to it -- the proprietary wireless connection kicks in and pairs the two devices instamagically.

Just like previous iterations of the Nike system, you can change the PowerSong, voice, and units. One new twist: a new Lock Screen pref that will alter the locked-screen display to read in portrait or 2 available landscape modes. Very handy if you have a mount on your treadmill. What, you don't have a mount on your treadmill? Me either.

Now, after pairing, you should have a shiny new app on your screen that has the Nike logo and a plus sign. Unfortunately, my sleepy morning eyes couldn't find the app, but a Spotlight search found it for me. Here's Apple's notes on setting things up.

Keep reading for a short round-up of how the unit works while running.

When Steve Jobs announced the new MacBook Pros, Apple received a lot of criticism for excluding a FireWire 400 port, despite the addition of FireWire 800. While most people were sitting around and griping, one company actually did something to reconcile the situation.

Sonnet has created a dongle that allows you to use FireWire 400 devices in your MacBook Pro's FireWire 800 port. The Sonnet Simply Fast dongle works with standard 6-pin male FW400 cables.

This dongle can be bought from the Sonnet online store, or from other retailers (i.e. Amazon) for around $14.24US. You can visit the Sonnet website for more information about the FireWire adapter. If you are looking for solutions to this FW 400/800 mystery then you might also want to check out FireWire 800 to 400 cables which are very plentiful, and might be slightly cheaper.
