A friend sent me the following- is it true or just another stupid internet
joke?

> THINGS YOU NEVER KNEW YOUR CELL PHONE COULD DO.
> There are a few things that can be done in times of
> emergencies. Your mobile phone can actually be a life
> saver or an emergency tool for survival. Check out the
> things that you can do with it:
>
> FIRST: Emergency
> The Emergency Number worldwide for Mobile is 112. If
> you find yourself out of the coverage area of your
> mobile; network and there is an emergency, dial 112 and
> the mobile will search any existing network to establish
> the emergency number for you, and interestingly this
> number 112 can be dialed even if the keypad is locked. Try it out.
>
> SECOND: Have you locked your keys in the car? Does your car
> have remote keyless entry? 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). Editor's Note: It
> works fine! We tried it out and it unlocked our car over a cell phone!"
>
> THIRD: Hidden Battery Power
> Imagine your cell battery is very low. 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.
>
> FOURTH: 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. If your phone gets
> 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.
> And, Finally....
>
> FIFTH: Free 411
> Cell phone companies are charging us $1.00 to $1.75 or more for 411
> information calls when they don't have to. Most of us do not carry a
> telephone directory in our vehicle, which makes this situation
> even more of a problem. When you need to use the 411 information option,
> simply dial: (800) FREE 411, or (800) 373-3411 without incurring any
> charge at all. Program this into your cell phone now.
