I got a new IPhone 4 days ago and have been struggling with this problem since. I finally went up the Starkey website and got on chat. Here is what he told me which worked. This should work with any type phone, but worked for me. I also have chargeable hearing aids, but it should also work by turning them off and on. We had a phone and two ipads so I turned off the bluetooth on them.
Please place the hearing aids in the charger. Please turn bluetooth off on all other phones and iPads that you are not connecting to. Turn Bluetooth on in the phone you want to connect to. Then on your phone, please go to the phone settings and then tap on accessibility and then tap hearing devices. Then take the hearing aids off the charger. On the phone, under MFI Hearing Devices you should see not paired and tap that and then tap pair when you get the pairing requests.
I hope this works for others.
