I have problem with GPRS connection, Clié via Bluetooth Nokia 6230i

before I have used Sony Ericsson K700, all working properly, Cllié connected via bluetooth to SE K700 and via GPRS to mobile service provider, now we have changed phones to new Nokia 6230i and is not working, looks like problem with GPRS device driver (mobile phone) on Clié, I have used general mobile phone driver, since I have no for this type of Nokia, ...is not working,
With a notebook (WinXP), GPRS is working, so I suppose it is not a GPRS problem

contacted Nokia support, they said it is a problem of Sony, that the driver is not availble ... tried some forums but this nokia phone is relatively new.

Can anybody advise or has similar experience ?

Thanks, Miro
