I just got text from this phone number

"Your entry last month has won you a free iPad. goto http://ipad.com.prizeform.com/ to claim it now - will expire in 245 hrs."

I think it is a scam.

I got it too, I did not participate in anything so I presume it's a scam.

And my message gave me a winning code...?

I got the same message at 11: am today, I didn't call, they also left a winning code number.
