I've just downloaded the Nokia PC Suite and when it says select connection, I select Bluetooth, then on the search and select phone bit it says 'cannot use the connection type check that all the needed hardware, software and drivewares are available'
My Bluetooth on my phone is switched on, and available for anything to view.
You might like to check system requirements for PC Suite here:http://www.nokia.co.uk/support/download-software/p
Can you send a photo to PC from your 5230 outside of PC Suite?
