Not reading SIM


Jun 10, 2011
Last night I flashed my captivate to CM& 1.6.3 that was then running stock 2.2. Phone is now recognizing that there is a SIM inserted but does not read it. I am making this conclusion because the SIM card icon with the question mark is not showing up in notification menu, but when i go to select network operator, it says none found and I have no service. The phone is also rebooting sporadically.

Is this happening to anyone else?
What should I do?
