I have been getting these calls since I got my Iphone 3 weeks ago but I have had the same number for 9-10 yrs. I took the time to register all my phones on the Do Not Call list and still get these damn calls. Everyone should complain about these unwanted marketing calls to the FCC and a letter to you congressman. I have gotten the same, "Iphone to first 1000 callers" ad from numerous numbers including all those listed above in addition to the one I just recieved a few minutes ago from 203-525-9721
I just filed my complaint with FCC and doing one to my congressman in few minutes.
I received a text message from this number stating they were giving away iPad2's to the first 1000 mobile users that go to http://cellrewardsnow.com. I forwarded this text to 7726.
