Maybe we should see this from the business point of view. When I hear about the "cell phone industry needing DRM and locked parts" I suppose that Dr Jaaski is thinking about the demands of carriers and the fact that most end users buy subsidized phones with what is basically "pay by lock-in". For this business model, the phone needs DRM and locks so that the customer can be forced to keep paying for the contracts and has no choice where to buy his software (music, games, ringtones, etc...). -- This is a good model for the industry, because it ensures a more regular cash-flow (regular payments instead of a one-time buy), and usually brings more revenues, since the total price is hidden (more than one young people ended up broke from their cell phone bill). But is this the only possible business model? Certainly not.
