I have a well taken care of (looks virtually new) C3000, Wifi card and USB Ethernet adapter for sale. Comes with a case, AC adapter, wifi card (Zoomax), CDs, card slot (SD & CF) covers. C3000 is flashed with pdaxii13 and works great.
I left it here for a while, so since that didn't work I've listed it here :
NOTE ; The Nokia 770 sold already. Thanks Da_Blitz !
Thanks for looking !
