I'm a bit freaked already with how much information the Android wants about you, where you are, when you go there, etc as I switch over from a BB. I am just setting up the new G2 now.

However, I'm totally confused (and not happy) that when I went to purchase my first app from the store, I was prompted with the last 4 digits of one of one of my cc's. Where did the system pull THAT information from? I haven't visited any website where I purchased anything to-date.
