NO WIFI OR BLUETOOTH after 3.0 update on my IPhone 3g

Thanks for the pointer, but none of this worked for me. No WiFi MAC address, Bluetooth MAC is all 0s.

Have you first 'select' the network again after deleting your favo network by tapping on the leftside of its namepanel so that the blue v-sign appears?

Same no wifi/no bluetooth problem here. These option are grayed out so I can't adjust settings. This occurred during the 3.0 upgrade today. I got an error during the upgrade, was redirected to an Apple error page. I had to restore the iPhone. Wifi still doesn't work. With this many people reporting basically the same problem, looks like we may have another gem from Apple. Makes you wonder about all those "I'm a PC" commercials. Maybe they should have "I'm a broken iPhone." I just bought my phone a month ago, just a few weeks before the new iPhone comes out.

No WiFi here on my original 4GB iPhone!

NO wifi here, its acting as if there's no hardware as its not finding any of the available networks my own or the neighbours 😟

I have done an update on my original iPhone and everything was smooth.

I have the exact same problem. My iphone 3g was actually working fine on 3.0, but I got a replacement from Apple because of poor battery life. Since replacements don't come with the latest firmware, i had to update. The wifi box is now greyed out, meaning you can't even enter the wifi menu. Same with bluetooth. I went to settings

Has anyone been to a genius about this? We need a solution!

Got my WiFi working by doing a phone reset (hold 'home' and 'power' buttons until the apple appears) and then forced shut down (because it FROZE at the apple screen). Restarted, put my ear piece in pairing mode and the phone picked it up. As for communication with my Intel iMac, it still doesn't work. Deleting the iPhone in the Bluetooth prefs and setting it up from scratch gives me the pairing password/number. The computer says the pairing was successful and that a port was created but on the iPhone I still have the spinning pinwheel and a "Not Connected" message. It all seems very "Microsofty" to me.

Upon updating, I also have a greyed out Wifi and Bluetooth. Anyone know how to solve the problem, yet?

Thanks for posting. I live in CA, but am traveling in Paris. I was just getting ready to update and decided to check out this site!!! I will wait until I get home. Don't want to screw up what works now.

What part of 'WiFi and Bluetooth are greyed out' do you not understand?

What part of 'WiFi and Bluetooth are greyed out' do you not understand? What part of 'no WiFi Mac address' do you not understand? What part of 'Bluetooth MAC is set to all 0s' do you not understand?

You mean you got your Bluetooth working this way, yes?

does apple not monitor these forums? should i just take my phone back to the store?
