I am using about 360 MB per month. I always go above 200. By my math, if I went to the 200mb plan I would end up at $30 per month. No change. If I go to the 2gb plan, at $25 I save $5 and would never go over. My fear is that new usage types of the phone that are not currently even developed will push me over 2gb and I will regret giving up the unlimited package. Does anyone fear this? I will probably never go over 400mb otherwise.
