If you want a dumb phone, why would you even care about locked app store? You aren't getting it to use the apps. Same for root capability; either WiFi hotspot works with your carrier out of the box, or you don't buy the phone. If you have to fight your carrier on that, hacking every device you use on the network is not a solution anyway. And a closed-source OS doesn't mean it's not hackable. Back in the day, you could mess a lot with Symbian.
