So I just went through a bit of a run around with AT&T. Bought a different phone with my upgrade, changed my phone number (which I guess resets the account), returned the phone, and went through a hassle of getting the upgrade reversed so I'd be eligible for the 4S preorder tonight. That's all well and good. But what's weird is, I have the 4 GB DataPro tethering plan. I used to have unlimited, but switched to tethering and lost my unlimited option. Now, when I look at my features, I'm set to "Data Unlimited for iPhone Enterprise" for $40/month. I also have the option to select the $30 unlimited iPhone plan again. What the hell? Is AT&T bringing unlimited back? Or did my account just get so screwed up that I'm seeing options no one else gets anymore? Pic below of my available data options through the AT&T website.
