Just a thread to make people aware of the "MyAtt" app that is free for download on IOS devices and allows you to quickly change most options on your phone/data plan without getting stuck on the phone with an ATT rep. For example, you can change your data plan, add or remove Hotspot Tethering, adjust Text Messaging, etc. This app let's you quickly make all these changes while you're on the go and it will show pop-up warnings when you are making each change to let you know how it will affect your plan.
