I have the incredible 2. I am about to upgrade and want to let my son have my old phone to use for games, email. It is not rooted. Is this possible? Will the phone have to use my current email or can I use his google email? will he be able to download games, twitter, etc? Of course, I am talking about with Wifi. Do I need to do anything with the phone before switching the service to my new one for it to work?
