Well, according to Fairleaks they are planning to sell 200.000 FP2. It won’t matter much, if they give some 100 to FP1-owners for beta test purposes.
As stated here, there would have to be a strict plan to follow and the beta testers of FP2 would have to compromise themselves to this plan and probably to send back the phone after the test phase.
I would very much like to be part of such a program!
