Some fancy hacks and a remote car key

1. Emergency numberThe Emergency Number worldwide for Mobile is 112. If you find yourself out of 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 while the keypad is locked. Try it out.
   
2. Locked the keys in the car? Your car has 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 home, call someone on your cell phone. Hold your cell phone about a foot from your car door and have the other person at your home press the unlock button, holding it near the 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).
   ( sure this wont work at least now .. Why ? First of all the remote car key does work on some radio signals and mobiles need to emit those radio signals which is not the case now ..so for this to work your mobile should transmit those weak radio signals from miles away ... yawn ..anyway somebody gets this working do let me know )
3. Hidden Battery powerImagine your cell battery is very low, u r 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 u charge your cell next time.
   (did'nt work on my mobile ... though some of the other mobiles showed a significant increase in battery level upto 30% )
