what u need is this

you need a bluetooth and gprs compatible mobile phone

u need to get the gprs setting from your mobile phone company to get to an internet gateway

you will then need to pair the phone with your pda via bluetooth and set the pda to use the bluetooth modem as a dialup device

you will also need a load more settings from your mobile phone company on how to connect and then you will be able to set up email etc

its a right pain in the arse
