Soo my upgrade is in a few days, and I've never had a smartphone before. I want to get the Inspire 4G, but I don't want to pay a whole lot for data. the 15$/mo plan sounds affordable, but will it be in the long run? I don't use email, very minimal web browsing, facebook, and never stream music or videos. I will also be on wifi alot because I am in an office alot with wifi. SO, is 200mb enough for me??
