Got same message for "test & keep" iphone5 and gives a website.  Scambook.com has this listed along with what seems to be multiple different websites used in the text messages.

Ditto...I received the same test message 2/14/12 but, with a 4578 validation code. I did a rev. phone # look-up for 6785458330 and it is unlisted according to the service I used.

I just got the same text message sent at 3:00am with a code of 3500.

I'm pretty sure it's bogus - but where is this coming from?

I received a text from 678-545-8300.  The text message read:  "Unreleased iphone 5. GoTo http:??iappletestandkeep.com & Enter Code 4964 Code valid 24 hrs"

Got a called from this last night, Monday, February 13, 2012. Text message actually, says " You are selected to Test and Keep Unreleased Iphone5. Go to http:/appletestandkeep.com" then it says valid for 24 hours.

I went to imore.com and found the following: "Scammers never miss an opportunity to scam, and while Twitter, forums, and email have long been subject to disgusting ?test & keep new iPhone/iPad/whatever? spam, it looks like the iPhone 5 version has taken to SMS. That?s right, not only are they content to waste your time and attention, they?re now also wasting your text message totals."

I tried the itestandkeep.com site and it is AmericanPrize where you have to apply for an or purchase items, such as credit cards or magazines, pay for them, and then your name gets entered for the FREE item. This scam has been around for a while. Advise your cellular phone company ASAP!

it's test and keep iphone 5
