I have an iPhone 3GS and iPhone 4, and want to use link2cell with a Panasonic Mobile Phone (KX-TG254SK - KX-TG7731 Base Model). Where in the iPhone manual or what is the first step to register with the Panasonic Phone?
I figured it out. I went to Settings on the iPhone, then General, Bluetooth, turned on Bluetooth, under Devices it showed KX-TG77, press that field, enter the PIN set on the Panasonic then press Pair. It will then show that device is Connected. On the Panasonic display it will show the Bluetooth symbol with a 1 next to it in the upper right corner. A second phone can be registered using #6242 (previous was #6241) and when complete, the Panasonic display will show the Bluetooth symbol and 1 over 2 next to it.
