A Trick to buy a New Mobile [-Mobo-]

You bought a Nokia phone about a year ago
and warranty will be soon over.
You wish you could get a new phone?

Well this is how to do it:
1) Remove battery cover and battery

2) Connect a 12V DC power supply to the phone's battery connector

3) An IC will then burn internally and your phone will die.
4) There will be no sign of it, so Nokia technicians won't see that you did something to your phone and will replace it with a new one.

Do not try this if your phone is not under warranty.
Do not try this if you suspect or you are not sure if your phone has ever suffered liquid or drop damage.
Do not try this if you don't understand what I'm talking about
