That was something I always wondered. Cell phones offer an amazing number of features now, but there are so many basic features that many of them are missing that I would love to have in one device.

AM/FM/Shortwave radio, VHF/UHF TV signal, FRS/GMRS radio, GPS, Compass, flashlight, laser pointer, ect. Sure, these features may not be as good as carrying a dedicated device, but at least I would have them all in something I usually carry every day. Instead of having to carry 12 other devices that take up space.

It amazes me that I can easily find a phone that will tell me the lottery numbers for every state, but I can't find one with a built in am/fm radio.
