I had this phone for a while (recently stolen in the ATL airport... ugh) and I had the same issues, and finally found out why. AT&T has not yet rolled out UMTS/3G service on the 850MHz band, yet! Their entire 3G infrastructure to date is running on their 1900MHz towers, with the exception of only one market in the United States, that being Oklahoma City. Don't ask me why.

Of course the phone only supports 850/2100 UMTS, so unless AT&T decides to roll out UMTS on their 850MHz towers, 3G users with only 850MHz radios are out of luck. :( I currently have a person who works for AT&T looking into whether or nor AT&T will be migrating UMTS service from 1900MHz towers to 850MHz, or turning up any new 850MHz UMTS service at all.

As of the current date, though, we'll have to deal with EDGE. :(

"Wtf? RAID 5 is the only way to fly, or stripe and mirror data on-the-fly, as it were."

Yes, because RAID5 works so well with only two drives.

As a follow up, the Airport card built in IS vulnerable.

I work for the company Maynor works for, that video was shot in the conference room. The vulnerability is real, and it hasn't been publically disclosed for obvious reasons. The reason it was video taped was so it could at least be displayed at Defcon -- obviously running that exploit over the air in a room with all kinds of laptops connected via wifi and sniffers would be a bad thing.

Maynor states in the video the flaw isn't Apple-specific, but at the time of shooting he was about 10/10 on wireless card manufacturers being vulnerable. It's a remote root exploit.

Hey, here's an idea. Let's completely bash a product/functionality that none of us have ever used!

I really don't want to open up a MS/Macintosh hellstorm here, given I own a Powermac myself, but I guess you could make the same argument about OSX 10.4's Dashboard and Konfabulator.
