I just got a SMS (text msg) from this number stating "Apple is looking for people to test & keep the new iPad 3! But only to the first 1000 users that goto http://theipad3.mobi and enter code BETA will receive it!".
I know better than that to go to something like this, so I have not gone to the website the number asked me to, but I want to bring this up for others who may have had it come up.
