I just got a Sony Erricson K750i off of eBay, but its locked to Virgin...

How does one unlock it without paying a great deal?

I used to unlock loads of nokias, but that was ages ago and Im out of the loop these days.

Your best bet is probably a local independant phone shop that might do it for a fiver, if that.

I think you can unlock with your DCU60 and a Da Vinci credit...
