I have the exact same problem as in a sticky thread concerning a V551, except it happened with my V66i phone.
The screen has gone dead but the phone works fine. If someone that has a V66i could tell me what keys I need to press to copy all contacts the the
sim card I'd really appreciate it. I can get to the phonebook menu (where the names of the contacts appear), so you can start describing from there. Thanks a lot!
