I have enabled the Benm tethering hack on my iPhone 3GS 3.0.1. I have tested it, and it works for me. My father is going in for surgery in a couple of days and my family and I will be staying in a nearby hotel that does not have Wi-Fi (or any in-room internet) for a few nights. Do you think if I tethered my phone with my Dell Mini 9 (with OS X) AT&T will find out? I'd only use it for browsing websites and iChat. I won't be downloading or streaming music or movies. Has anybody else used tethering for tasks like this for a short amount of time like me? Should I be worried about anything? Thanks.
