While phone cases are great accessories for any phone, what happens if the case and all other accessories strapped onto your mobile device get lost? The Zomm Wireless Leash Plus' new accessory has the answer, as it will let people find their lost iPhones.

The device is a small Bluetooth piece of technology that will warn people when they are about to leave their phone behind and helps find the phone, keys and and anything else the accessory is strapped to.

"After pairing was complete, I left my iPhone on my desk and went for a walk," Steven Sande said in TUAW's review of the device. "Once I was about 30 feet away from the iPhone, the Leash started vibrating and flashing its LEDs. After a short while, it began beeping, and a few seconds later the volume of the beep cranked up. Let's face it — the Leash is definitely going to get your attention. It works the other way around, too. If you have your iPhone with you and leave your keys somewhere, the Leash will start beeping."

The Leash costs about $90. Sande's review said this is a unique accessory for the forgetful people out there who may not want to lose their iPhone and have to pay the money to get a new one.
