I am on call this weekend - was talking to a patient when all of a sudden the call cuts off. (no land line, so i have to use my eris on call) -- I push the trackball to light up the screen and nothing happens. Then a few seconds later the bootup screen starts (where it says 'HTC - quietly brilliant). The phone was fully charged...anybody ever have this happen to them? I rely on this phone to reach patients and other doctors...am not happy about this.
