Smart Phone Security Tips . . . Use a password. It takes a few extra seconds to sign on, but it's worth it to protect your privacy and keep spyware from watching you. For a guide that covers the common smart phone systems, click here. Be smart. Assume you might lose the phone (horrors!). Don't store bank account, credit card numbers or other sensitive information. Depending on the system, you can download a tool that will help you locate your lost phone and wipe out the information. Choose apps selectively. Download applications from sites you trust and read the user reviews to learn from the experiences of others. Don't click on links or call phone numbers sent in emails and text messages. People are three times more likely to click on a link on their phone because they tend to rush. Search for "mobile security" in the Android Market or iTunes store for an app that will stop you from inadvertently downloading viruses. Be wary of public Wi-Fi networks. Eavesdroppers may be able to see your data on web-enabled phones. Only use wireless networks you trust.
