Received a text message saying that I had been randomly selected for a Free New iPad 2.  Get it now at

When I put that address in the url, it cannot be found.  Therefore, it is a SCAM

I don't answer calls from numbers I don't know.  I ignore them and If it's important, the caller should leave a message.
