Just got sent this stuff in some chain mail but thought id post it so people can test it

Have you locked your keys in the car? Does you car have remote keys?
This may come in handy someday. Good reason to own a cell phone:
If you lock your keys in the car and the spare keys are at home, call
someone at home on their cell phone from your cell phone.
Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock.
Saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other 'remote' for your car, you can unlock the doors (or the trunk).

Hidden Battery power
Imagine your cell battery is very low , you are expecting an important call
and you don't have a charger. Nokia instrument comes with a reserve
battery. To activate, press the keys *3370# Your cell will restart with
this reserve and the instrument will show a 50% increase in battery. This
reserve will get charged when you charge your cell next time.
AND

How to disable a STOLEN mobile phone?

To check your Mobile phone's serial number, key in the following digits on your phone:
* # 0 6 #
A 15 digit code will appear on the screen. This number is unique to your handset. Write it down and keep it somewhere safe. when your phone get stolen, you can phone your service provider and give them this code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally useless.
You probably won't get your phone back, but at least you know that whoever stole it can't use/sell it either. If everybody does this, there would be no point in people stealing mobile phones.

First one was tried on Brainiac.

The "hidden" power is actually there for when your main power runs out, without it your phone will loose all its settings, time into etc.
