Mobile Bluetooth Hacking:

Here is a list of what you can do when you have hacked the other phone. Have Fun!

Read Messages. (They are no more personal!)
Read Contacts. (Check your lover’s phonebook to see what name he/she has saved your name. Hey, please don’t suicide when you see he/she has saved your number as lover no. 9! HeHe)
Change Profile (Change the other’s profile to silent mode when you are on a date!)
Play Ringtone even if the phone is silent (Annoy your classmates!)
Play songs from the hacked phone in the same phone.
Restart the phone (Show some magic to your friends!)
Switch off the phone (Ultimate thing that you can do!)
Restore Factory Settings (Do this to the most organized one and run away quickly!)
Change Ringing Volume (You have enough experience how to use it. Don’t you?)
