You're on a trip. You want to order in pizza. What's the easiest way to do this on your iPhone? Open up Maps and tap the "locate me button" at the bottom-left corner of your screen. Wait for Google Maps to find you and then type "Pizza" into the search box and tap Search. Maps automatically searches near the "locate me" results--finding all the pizza delivery services near your actual location. Tap on any blue "disclose" button to find the phone, home page, and address for each item.
Of course, you're not limited to pizza. Search for shoe repair or pediatricians or any other retail type or service.
Yes, I tried it and it works!
