Have an iPad 2 and my wife just got an iPhone 4. Before she got the new phone we connected our phones to a Panasonic cordless answering system (model #KX-TH111) via bluetooth. We have tried to connect Her iPhone with no success. The phone "sees" the TH111 but fails to register. The phone's bluetooth is working because it connects to her car's system. Panasonic states that it conforms to HFP protocol. I have also tried to register my iPad but had the same results. Can anyone help here?
