I've noticed the questions that people are asking can also be related to apps on the marketplace or on the phone, along with google search.
"What's my carbon footprint" ---> Ecorio Travel Green App
"Can I get this cheaper elsewhere" ---> Numerous Barcode Apps
"Which way to the convention" ---> Google Maps & GPS
Only problem is they don't tell you these apps exist in that commercial, you have to already be familair with the phone to know this.
