I want to explain you the procedure to track your mobile. Now a days mobile bacame very compulsory and many people are using very costly mobiles for best features.
So we have to know what we should do when someone stolen our mobile.
Here is the procedure you have to follow.
Every mobile has a unique number called IMEI number i.e International Mobile Identity number. To know the IMEI number of your mobile just press *#06#. It will display 15 digit unique number. Note down this number anywhere but not in the mobile. ok. If your mobile is stolen, just email this IMEI number to this mail id:-
cop@vsnl.net
No need to give any police complaint. They will find out where your mobile is within 24 hours though they changed the SIM.

I think its very useful to all of you.
Beware of thiefs and aware of the actions.
