My wife doesn't like the UI on the phone, she wants her old Sanyo 4900 back (she lost it).

I'd trade her the Sanyo 5400 I have for it, but due to Sprint having a different idea of plan than I do, and me being unwilling to argue, having a bluetooth phone and the treo would be useless, as i could only have vision on one of them unless i change plans, and i'm not doing it.
