if you use bluetooth you don't need the USB lead. The PC suite only works with bluetooth and therefore you can do more with bluetooth than you can with the USB lead.
So why do nokia supply the usb lead if you need bluetooth to transfer data to the n-gage.do u need the cable connected to the n-gage and a bluetooth card installed the first time you install the software that comes with the n-gage.
I have installed the n-gage Pc suite and conected the n-gage to the computer via usb lead suppied ,what else do I need to do?
to access soem data on your NGage, all you need is the USB Cable and the windows Explorer. When you connect, it will show as a HardDrive. Therefore you do not need the Software coming with the NGage.
I think its recommended tho, since its basically especially for that phone.
To use the Nokia Audio Suite, the program where you can put mp3s and Audio files onto your NGage, you will only need the USB cable.
To use the NOKIA PC Suite, with which you can transfer and access fils and do some neat things with your NGage (i have no clue, i dont use it), you will need a bluetooth stick/dongle...
