Anyone using the MBA w/ATT's new 3G USB modem -- USBConnect 881?

The 881u fits in the port very well and works great. Just make sure you go to Sierra Wireless and get the latest driver so it works directly with Leopard instead of using the Sierra Watcher program.

I average about 1.4 mb down and 1.3 mb up in the Wilmington, DE / Philadelphia, PA region according to the Speakeasy speed test. Didn't try the speed test outside my home area, but it seems much faster than my Verizon EVDO when I've used it in Jersey City, Manhattan (Financial District & Midtown), Denver and Los Angeles (Woodland Hills). The difference is really noticeable if you are on a low floor or in the center of a building.

Worked fine for me after downloading the driver from Sierra. After running it once, you can also go to your network location. You will see a new PPP modem device called 'launch2net PPP Service."

If you add the phone number: 99**1# , and go to the Advanced Settings, select the Sierra GSM modem driver in the two popup lists, leave the rest at default and save, and show the modem in the status bar, you can forego the SierraWatcher application and start the connection from the menu bar. You will not be able to tell, whether you have 3G in the area.
