Does anyone who surfs the net from their cell phone know what their approximate usage in KB or MB is (and care to share it here)? I'm trying to choose a new plan and want to have an idea of how much data I'll be using. I don't plan on doing heavy surfing but probably occasional email checking, googling, phone number look up etc. Probably I'll use it more than I think I will if it's convenient so I just want to know what I might be in for? Is 5 MB a month a very small number or fairly reasonable?
