Losing your iPhone can be quite painful. Unfortunately, that happens to too many folks. You could always use apps to locate and remotely wipe your phone. The better way to approach this is by making sure you don’t leave your phone behind. These Bluetooth locators help you find your phone before it is too late:
Nio The iPhone/iPad Anti-Loss, Anti-Theft Accessory: pairs with your iPhone and alerts you when your phone is too far away from the tag. You can customize distance settings and alarms.
Kensington K39565US Proximo Fob and Tag Starter Kit: compatible with the iPhone 4S and iPhone 5. Attach it to your camera or anything you want to keep track of and this will help you recover your valuable items. The Proximo is a proximity monitoring system, so you always know where your iPhone is.
BiKN: lets you use your phone to find your stuff or use the tags to find your phone. It is available for the iPhone 4/4S.
Wireless Leash Plus: not only provides you with a panic alarm and one touch 911 access, this also alerts you if you accidentally misplace your phone.
StickNFind: a Bluetooth powered small location sticker you can use to find your valuable items. Just stick these to any device, person, or animal, and you will be able to find them using your smartphone. The stickers have a range of 100 feet.
Losing your smartphone is not fun. The above products are not 100% foolproof but they do give you a better chance to avoid leaving your phone behind.
