As I just responded to someone above .....
I also received this same text to my work Blackberry on 12/06/12 @10:54AM (EST).
They wrote (same as yours):
Got a text that read " Michelle said to send this to you http://bit.ly/Vz2uWg".
Good thing I checked online as I havve a hateful Step-daughter named "Michelle". @(-_-)@
I was sent a txt message today 12/23/12 from a Michelle. Text message reads: "Michelle said to send this to you http://bit.ly/W0sCUx". I went to this website and McAfee told me that this is a dangerous site to go to. So, everyone be warned,if you get a text from Michelle, do not go there.
Got the same message at 12:56 AM Pacific Time on December 24, 2012 saying "Michelle said to send this to you http://bit.ly/W0sCUx", except that the message came from 248-326-8019.
