Dial M for Memory

At the end of 2003, nearly 160 million people were using cell phones, according to estimates by the Cellular Telecommunications and Internet Association. And, according to research firm Gartner Group, some 250,000 of those people lose their cell phones annually. While the phone itself is easy enough to replace, it's the valuable database of information that proves a much harder resource to restore. The solution: Back up all the information stored in your phone.
