I'm just wondering if anyone knows of any advantages of getting the ATT version of the phone over the international version that's unlocked. Will they both perform the same on the ATT network? The unlocked version is a bit cheaper than the ATT version, and you can save on sales tax, too. I just don't know if I'll run into problems for some reason that I don't know about. It's important to me that the tethering works, because I need that for work. My plan allows it.
