As I understand it, when I upgrade to the iPhone 5 I will lose my unlimited data plan and have the choice of 2GB for $30 or 5GB for $50 (at least that's what the Verizon chat rep told me). My question is how much more data will LTE use than 3G? For instance, if I surf the web for 30 min on LTE, does it use the same amount of data as if I were surfing the web on 3G for 30 min? I am just trying to see which data plan I should get. Thanks.
