Not that this is a full solution to the problem or directly responsive to your question, but it is possible to order a FP4 from European distributors, ship it to the US, and have the phone work far better than Terracube or many regular US cell phones. That said, I’d give a significant donation to to FP4 or any other organization if it sped up the North American distribution process. We desperately need a fully-supported FP4 here, and I think it would do quite well.
