I wish the N950 was fully released, there were some produced but I don't think it was commercially available. It was the true successor to the N900, it would have used the N9 software but unlike the N9 it also had a physical keyboard.
yeah I scooped n950 on some online marketplace for very cheap since it was bricked, fixed it and resold it for profit, but what a beauty of a phone, I wish I kept it.
