Suddenly my Nokia N9 stopped working in the midst of a phone call. It showed an error about the SIM card. I replaced the SIM card with another one, rebooted, reflashed but nothing seems to fix it. When I try to get the IMEI code (*#06#) I do get a long beep but no IMEA code shows up.
Has the phone function died on this brand new N9 (I only have it for about 4 weeks)? Any tips, hints on how to solve this?

Thanks,
Rob
