To change the direction of this thread a bit I got a call yesterday on my Sprint cell phone from 303-720-1234. I had no idea at the time where area code 303 was so I let it go to voice mail. But they didn't leave a message. So today I tried to call it back and got a "no such number exists" type of message. And I can't find anyone with this number via Google searches and don't really want to pay for more information.
Now to be honest it looks a bit bogus to me. 1234 and all.
Anyone in the 303 area care to try and call it locally and see what it is?
