Put in a SIM card from the carrier to whom the phone is legitimately locked. Then the phone will recognize the SIM.

Thanks guy for such suggestion, as this sim card is legitimate and WAS working perfectly and again I wish have not updated it. I will be more careful NOT to suggest anyone for update.

Don't be so touchy. Over 90% of the people writing in have this message from jailbreaking. If you haven't, then try a new SIM from your carrier.
