I was wondering if anyone has done an experiment to see how much data the Maps app uses serving up all those Maps and 3D renderings? Now that Verizon and AT&T are steering us away from the unlimited plans, I'm wondering how much more data I'll be using each month if I use Maps to drive back and forth from work and home each day for my 2 total hours of commute time. Anyone tested that? Maybe check to see how much data you've used before starting Maps, and then how much after? I haven't upgraded yet, otherwise I'd test it myself.
