Got a text message from this number on March 23rd at 8:26 a.m. (Pacific time) stating; "Apple is looking for people to Test & Keep the New iPhone5! But only the 1st 1000 users that enter code BETA at http://testiphone5.mobi Receive it!
I obviously didn't reply to the text message - and would highly suggest that no one else does either. ** more than likely spam message **
