Can you tell us if ATT detects it? A comment on the youtube video says they did, but if that's not the case, I may try it out. Seems to be the most slick and easiest way to tether.
I wonder if you could claim ignorance. As in you were reading about it in anticipation of them offering it and you acidentally installed the file and later you plugged your phone into your pc to sync with iTunes and you thought you were using starbucks wifi the whole time...
I experimented with it and racked up 400 megabytes in data transfered without even trying (Checked e-mail, visited some web pages).
If AT&T then charges me 0.60/megabyte as stated in the Youtube comment, I'm looking at a pretty hefty bill this month.
Same here. I just moved and don't have internet set up yet. It's been really useful, but I'm a little worried about my next bill :).
