I have iPhone 3GS and suddenly it's gone away. I mean WiFi, bluetooth is not working, and I can't make any calls.

Here's a screenshot:

No wifi, no BT, no network

Any help will be appreciated!

I would guess this has been IMEI blocked through the carrier. – cregox Mar 17 '11 at 15:11

Wow. Seems like the modem/baseband part is gone wrong. Try rebooting the phone. If still not working - backup your information (from iTunes) and try a restore to factory settings (I'm assuming a factory unlocked phone, no JB). If this doesn't help - probably it's a hardware failure.

About the IMEI blockage - no, it's not the case.

Yeah, I have seen a firmware update go wrong and do this, and the actual hardware go wrong and do this, :( – ConstantineK Apr 17 '11 at 13:05
