Motorola Debut i856
If the SIM card is in the phone will get all the way to the main screen. From there it just freezes. Doesn't respond to anything.
With the SIM out all the keys still work.
Also when you try to shut it off, with the SIM card it freezes are "Powering down".
This really ticks me off since I paid $100 for it and I can't afford a new unit.
