This is a version of the gift-card-offer scam   http://www.snopes.com/inboxer/nothing/bestbuy.asp

received a text message this morning saying "Your entry last month has WON! Go to http://bestbuyprizes.net/ and enter code 4787 to claim your FREE $1000 Best Buy Gift Card within 24 hours!" Lord knows I did not enter anything anywhere to win a gift card for Best Buy.
