I've used 107 MB of data since I got my iPhone 5. I normally use less than 100 MB a month - I pretty much only use cellular data for receiving and (rarely) sending email when not in WiFi range - about 2 hours max a day.
My only guess is that Maps is eating data, even though I haven't been actively using it. At 107 MB in 4 days, people on lower data plans (like me!) could get some nasty surprises on their bill.
