I have a big problem. I did a complete wipe of my iPhone 4S.... Data, Settings, everything... so my phone had to reactivate. I walked through the steps just as if it were a NEW phone.
I can't turn Bluetooth on. Period. I try to switch it to On and it just flips back to Off.
I am going to try and reboot my phone and see if that fixes it. The only things I did before I tried to turn on Bluetooth was setup Nike+ and set up iCloud.
Restarting my phone fixed this. It immediately showed up as "On". This is definitely a bug but thankfully a restart fixes it.
