I'm on the $50 plan. I wanna go old school. I like both phones just do not know all the pro's and cons of the phones on boost network. I'll research the fixes for each of the phone. I want to know what everyone thinks.
Probably the best place to start searching would be the Nextel forum here about both phones, but here are some features that would differentiate between the two: the i930 has triband gsm (900/1800/1900) bands in addition to iden, so an international phone of sorts. The 8350i bb has wifi so you can surf the web better at wifi hotspots.
