For a sandboxed baseband check out the Neo900 project.

It seems interesting. But they want an address just to create an account. At least they don't demand a mobile number ;) And the only payment options are bank wire and PayPal. I don't see that they accept Bitcoin. Also, I see no option for anonymous fulfillment.

Thanks, programmernews3 :)

DocScrutinizer05 says on IRC that neo900 will accept cash by mail and Bitcoin. And "anonymous fulfillment" (on-site pickup, I presume) for wholesale (N>50) orders. Cool. Someone could sell them for cash at conferences, etc.
