Do you expect that comparable use with an Android phone will equal similar data usage on the 4S? Or do you think that iCloud and Siri will end up pushing data use substantially higher for this phone? The only reason I'm asking is that as a current Android owner who uses less than 1GB per month, I'd like to see if I can keep data use under the 2GB tier cap... or if the features of the 4S mean that I'm going to go over. While I'd like to pick up a 4S, I can't afford to be jumping up to a higher tier of data. I'm currently with Sprint, but (despite their unlimited data) I am sick them and their policy and price changes. However, if I can't fit into a 2GB tier, I'm not going to bother.
