radp... welcome to the BBForums. We (normally) aren't a bunch of jerks who get mad at first time posters... so no problem.

If you SIM window as you described stated all was "disabled", the the device is unlocked from the branded carrier. That should not be a problem. You won't get a prompt or message to enter an unlock code again after inserting the SIM.

But, do you get any message at the top of the 8800 screen, such as SOS?
