Root Giving my rooted phone to my bro, what should I do?

[duratime]

Sprint is allowing me to upgrade again, and my younger brother has been bugging for a new phone. I have a brand new BB bold for him, but he wants an android. It makes sense for me to keep the BB for a back-up for one of my employees. My question is, I have rooted the phone and installed EF02 on it. To be honest, I think the phone works real well this way, but I'm worried about leaving it this way. My brother has no geek abilities, and will be going back to college soon. Do you think I should return the phone back to EC05 or keep it at EF02?
Thanks

I would say ODIN back to EC05...unless there are any apps that you have shown him that he may want to use. That way he can get the official EFxx update.
