Mobile phone platforms are reverting back to the pre-iOS/Android reality where you have to jump through tons of hoops to even make an app let alone run a viable business with it.

AFAIK in some countries (US?) phones were usually sold locked in a sense that you could only install J2ME midlets published by your mobile provider, who'd nickel and dime both users and devs for the privilege.
