I have a question regarding at&t and being grandfathered into the unlimited internet option. If I decided to get a new phone that was not an iPhone, will I still be eligible to keep the unlimited internet option? If a phone supports LTE, am I required to get an LTE plan or can I continue to use the 3g plan I currently have? I'm not really interested in LTE, but am interested in looking at some of the other upcoming phones in case the new iPhone doesn't interest me.
