I was on the AT&T "unlimited" plan for a long time. I really thought they would have to force me off it because I wasn't going to budge. I am on my iPhone 4 a lot with browsing, emails, FB etc. Same with my iPad. However I also try to hookup to a WiFi source wherever I could. That being said, I did a 6 month data analysis for the three devices on my plan. Monthly average; 1.15 gb. I was paying about $220/mo. I went to the dark side and went with the 6gb data share plan. Even with 4g (no LTE yet, some decade) I don't think I will break 2. I am now at $170 out the door. $50/mo savings. It is true, every man has his price.
