Anyone else having a problem with this? I hadn't used Bluetooth on my iPhone 5 until this weekend when I'd downloaded Instashare and was testing this with phone, iPads, and MBA. Instashare is a nice simple app for transferring files via wifi or Bluetooth. Ipad4 dropped in and out, ipad2 was rock solid connecting with everything, the MBA also. iPhone was hopeless. I tried to pair it with MBA with Bluetooth, MBA said it paired successfully, iPhone couldn't connect and said "not supported, forget this device." So, I switched Bluetooth off on everything else, and tried to pair iPhone with apple wireless keyboard. It couldn't even find the keyboard, so it seems Bluetooth doesn't work at all on my phone. I will ring apple this week, but wondering if anyone else is having such problems, so I can try to figure out if it is an OS or hardware issue. I'm running latest OS on the phone (and on iPads). Also, since last OS update, ipad4 won't connect with Logitech k760 wireless keyboard - it did before - but it does still connect with apple wireless keyboard. Ipad2 still connects with both, and has same OS. So ... It's confusing.
