my 6630 exhibits problems whenever there is no signal for extended periods of time. programs like calendar and notes take an insane amount of time to open (if at all).

i've also noticed that, during long periods of time without a signal, the "Network Mode" field in the "Network Settings" tab in the "Settings" folder is blank (instead of either GSM or Dual Mode)

this problem, once it appears, does not go away even if the phone reacquires the signal.

i've tried reformatting the phone and putting the phone in GSM mode, but those don't work. what should i do?
