Generally when people buy phones (yes its a phone for most people, i doubt people carry a second device to call mommy and daddy), they expect them to work. PR. 1.1 Works. If they would release an unfinished PR 1.2, as some would like it to be, it would be disasterous. OTA updates pop up automatically when you go on the net. I would assume 100% of the users would update. Yet maybe 1% know how to reflash their device. Imagine the troubles that would create.
