No service (No SIM card)

[imljsilver]

I get this message with a known good sim card: i.e. it works in another phone.
I have already tried factory reset and have gone back to 2.2.1 but still no joy.
If anyone can help me fix for this I'd be most grateful.
Thank you.

Thanks Mesang, have tried that already. And the phone's way out of warranty.
