Can you set up the developer mode using a smart phone
That sounds like a question for the Developers' Forum.
Unless I'm missing something critical, the only thing you'd use the phone for would be as a hotspot. You could accomplish the same functionality with a standard WiFi connection.
I'm gonna suggest you go the Developers' Forum route for that kind of information.
