This the reply from Nokia Careline, when I was asking information about 6030 data cable :
Dear Mr. xxx,
Thank you for emailing Nokia Careline.
In response to your inquiry, please be advised that the Nokia 6030 unfortunately does not support synchronisation with a PC. In addition, this particular model does not support USB cable connectivity options.
Furthermore, kindly be informed that the easy flash connector located on the phone is solely for service suppliers to upgrade the software of the phone. In your daily use of the phone, kindly avoid from touching the easy flash connector area
We hope that this clarifies the matter and we apologise for the inconvenience caused.
For further assistance, please contact the Nokia Indonesia Careline between the hours of 09:30 - 21:30.
