A friend of mine visiting from Dallas last night was telling me about GrandCentral, a service that allows you register a phone number and have any calls to that number forwarded to your real number.  My friend has a season tickets to the Dallas Mavericks and sells his tickets.  He sells the tickets through craigslist and doesn't want to reveal his real phone number.  GrandCentral work much like I the spam management tools I wrote about recently.

Iowa is not in the list.  So how does an Iowan sign up for GrandCentral?
