just got a message from this number except its to win an iphone 4s and the first 1000 users go to http://iphone4sfree.mobi and enter 7777 will receive it. they spelled received wrong though

message::  "The brand you love is looking for testers for the iPhone 5!  The first 1000 to enter code 7777 at http://iphone5tester.mobi get to test & keep a new iPhone 5."  

I use a Virgin Mobile phone with no desire to upgrade to an iPhone service.  I pay 15 cents a message to view what I consider junk mail, and I do not appreciate getting these.  I will not do any business with anyone contacting me in this way.

Got a text form (201) 423-2528 stating:  You've just been Chosen tho Win a 1000$ BestBuy Gift card! But only the 1st 1000 users that goto http://giftsfrombestbuy.mobi and enter 7777 will Recieve it!
