This call made at 4:15 AM, Apr 17 informed me " Your latest entry into our contest has made you a winner! Go to http:/bit.ly/IXeU1o to claim your iPad, enter code 9857 to qualify.  Claim before 4-18-12."

I am not responding because I did not enter any contest.  Secondly, even though the message shows it being sent on Apr 17, I'm sure it was not their on the 17th, probably sent on the 18th which would have made me too late even if it were a legitimate contest.  Sounds like a scam.
