My father works as a dry waller, so we got the ic502. I am 12 and the smart one, he made me set up the phones. My phone started right up, and i called in set up my service. My dads phone would not even start, just a blank screen. I spent probably 2 days on and off talking with nextel. After all that time they just decided to send my dad the ic602. that phone worked fine, but then my ic502 started acting up. When I would turn it on, I would have to press the power button 3 times! The phone stopped charging, so my dad has to charged my batterie in his phone. I hate nextel/sprint and cant wait till my 2 year agreement ends.
