<Warning - Voda can't unlock their own Nokia 6680's
I have written up the start of this before - and aI will write up a detailed account later, but for now :
For everyone that buy a Nokia 6680 from Vodafone - their helpdesk has just given up on unlocking the Nokia 6680 they supplied us with, as they are unable to get unlocking codes.
They even told me to take it to a streetmarket or similar to get it unlocked, and they would refund the cost. But it turns out that none of the “normal” places that unlock mobile phones will not unlock 6680's.
So the phone will be sent back... >
