The number leads back to something called predicto.com. I called both predicto and heycosmo and told them they contacted an secure internal government mobile phone and they were kind of scared when i threatened legal action.
On 11/16/08 at 4:59 PM, I received a two-second call from 302-336-7405, no message left. Since 302 is a Delaware area code and I have relatives in Delaware, I called back. The answering message said something about Predicto and told me to punch something (star?) to get a text message. I hung up and googled the number, which let me to this page.
