So the wife wants to upgradjya when the new iPhone 5 comes out this year. So I can have her old 3Gs. I currently have a $#@!ty old Treo 350 that I have with Sprint. Don't want to change my carriers as I have a $15 a month employee plan that somehow is still hanging on. Can I jailbreak her iPhone and use it with my Sprint service? If I jailbreak it, can I still put music on it and sync it with a Mac?
I have searched online but can't find anything definitive. The Treo does not have a SIMM card.
