I am studying in college at Florida and I have got a lots of friends who like to play pranks in between. I am having a cricket wireless connection on my cell.Yesterday I got a call from a unknown number sharing some really serious information. I just wanted to confirm whether it was really serious or just another prank by my friends who likes to do such stuff on daily basis. Any information on where to look up cell phone number. Please mention any sites you have tried before which could help me along.
