3G Bluetooth not turning on in settings after OS3 (spinning wheel)

I've got the exact same error on my iPhone 3G as you, except that it worked fine for a month or so after upgrading to OS 3.0. Pairing, syncing and tethering has been working with no problems.

I don't use bluetooth every day, so I've turned it off and on many times to save battery, without any problems.

But suddenly today, it won't turn on at all... only a spinning circle and then back to off 😟

I also searched, and tried some of the solutions you did, with no luck:
- turning airplane mode on, waiting 30 sec, and turn it on again
- turning the phone off using only the power button, and turn on again
- holding power + main buttons down untill it reboots and apple logo appears
- settings > general > reset > reset network settings
- settings > general > reset > reset all settings
- iTunes restore

Also tried the following combi (which apparently helped some 2.x users):
- Hard reboot iPhone. Press and hold the home key and power key together until screen goes blank and the boot screen is displayed then release.
- Enable Airplane mode.
- Enable Bluetooth. This will dis-engage airplane mode – pls note it still won’t enable.
- Press the home key and return to the settings menu.
- Enable Airplane mode.
- Disable Airplane mode.
- Enable Bluetooth.

Nothing works, still shows "0". I can't activate the button so it goes blue and shows "I" 😟

ANY help would be VERY appreciated.
I bought the phone 2 moths ago, and have not jailbroken it or anything.

Thanks in advance.

I am having the exact problem, everything works fine, but Bluetooth just won't turn on....help

Are you SURE you did a RESTORE through iTunes and that didn't help? Try a new restore, select "restore as a NEW iPhone" (I know it's there somewhere) and DO NOT apply the backup right away. That way, the iPhone will work as brand-new device.

This should be definitely a software issue, so a restore is the last resort. This issue has been around the forums for quite sometime. I guess you should all do some digging in case you find a solution.

Still no solution to this?!?

Now running v. 3.1.2, but still no bluetooth 😟

Hello,

I got the same problem. I got an Iphone 3G 16Go (Firmware 3.1.2), and I can't turn on Bluetooth.

I even have done a hard reset (restore as new iphone), but I can't manage to turn Bluetooth on.
When I turn the switch on, it spins for about 10 seconds and then go back to 0.
I tried with an headset in pairing mode and with the Bluetooth in my Macbook on, but it didn't work.

I tried the various methods with airplane mode on/off, reset device, shutdown device, but nothing works.

Does anyone have an idea how I can make the Bluetooth work?
Any advices are welcome.

If restoring through iTunes (restore as a NEW device, don't revert to a backup) doesn't do the trick, the best possible explanation would be that you are facing some kind of a hardware problem; if this is the case, I suggest you take your iPhone for service.

Ok. Thank you for the advice.
I will contact the service.

Same issue and couldn't find a solution yet. Did anyone figure it out yet?

Same problem here.

one day, suddenly, bluetooth worked (i. e. the I blue switch showed instead the grey O. Then it did`nt

Restored iPhone (as new) and it worked once. Backuped data and started to work
Restored again and it didn't work no more.

****** off because I paid for a change of iPhone because the other one couldn't use wifi and now this one doesn't bluetooth. I am not in warranty as far as Apple is concerned but I am in warranty this phone provider movistar in Spain. But this guys are real crooks and they don't repair anything.
