- Use a screen protector to prevent scratches

- Get a really good case like the Otterbox Defender Series (with three protective layers: hard polycarbonate shell covered by silicone skin plus built-in screen protector) or Ballistic's Hard Core case (built-in screen protector and hard shell with shock absorbent polymer and silicone outer layer). Very few promise protection from water, but the LifeProof iPhone case promises protection up to a depth of 6.6 feet.
- Turn on the phone's automatic back up to prevent data loss
- If your phone gets wet, remove the battery and SIM card and let it completely dry. Don't use a hair dryer. And don't try to use the phone, which could allow water to move deeper into the phone's electronics.

- Set up the phone's built-in security by turning on screen or keypad lock or requiring a code or pattern to unlock device access
- Clearly identify ownership either by a simple ID sticker or an app like Contact Owner, available on Google Play, for Android or Owner Information, available through iTunes for iPhone. Both state the owner's contact information right on the locked screen.

- Download a free or inexpensive app to help locate your phone or lock or wipe the phone remotely if it gets lost or stolen. Some popular apps: Android Lost, available on Google Play or Find My iPhone, mentioned above.
- Already lost your phone? Try Plan B from Lookout Mobile Security, mentioned above. The Android app is pushed to the missing phone where it launches, turns on GPS and messages the phone's location back to the account holder.
