With the upcoming release of the newest iPhone, it will be time to upgrade from my Verizon iPhone 4. However, I will probably keep my old phone. I have tried to google how to set up my deactived phone for use as an iPod touch (or iPad mini mini) , but am not having much luck finding the correct answer. So, what are the first steps I would need to do to keep my old phone useable, and other than iMessage and Facetime, what will it no longer be able to do? Thanks for the help.
