You might enjoy your cell phone's ability to play music and manage your calendar, but if you can't use it to actually make a phone call, you're not going to be very happy. That's why phone companies love to show off their stellar coverage maps. Unfortunately, real world coverage often looks somewhat different. I've got a tool that helps you bridge the gap between your cell phone's ideal coverage map and what you can expect in real life.
DeadCellZone is a Web site that lets you see real-world holes in your cell phone service's coverage. It generates its data from actual users, who file reports on dead zones all over the country. There are about 100,000 complaints in the system.
Just enter a zip code, city, or a specific address, and you can see a map with detailed results for AT&T, Sprint, T-Mobile, or Verizon. Not only that, you can even drill down to specific dead zones and read comments about the site.
Enthused? You can even submit your own problem reports, which are then incorporated into the site's map. There's a version of the site optimized for your iPhone as well. [via MakeUseOf]
