Just got a text saying the same thing, sounds like a scam. Exact text:
"Congratulations, your number has made you Apple's Winner! Goto http://www.apple.com.ca.llhf.net and enter code iWin to claim your Apple product!"
PS: I live in Canada.
PPS: I'm not sure if the first two letters of llhf are lower case 'L' or upper case 'i'
