Blue tooth

Hi,
providing the mobiles that your trying to connect to are, bluetooth capable devices themselves. it,s the matter of getting the 2 devices to find or recognise each other ( connection Manager ) or device enabled settings.
If your mobile phone is Infa red then the 2 are incompatable. This can sometimes be determined via a little blue flashing light ( hence Bluetooth )
refer to your PDAs user and instruction guide for further assistance.
