Hi guys,

I bought a k770i a year and a half ago and had it unlocked.

Well, the other night I had the brain wave of updatin the phone through sony's site, and not its locked.

I've never tried unlocking a phone myself.

I've got no idea where to start with this, from what program and files i need etc and I don;t fancy having to find someone to pay to unlock it yet again.

I'd be very grateful if someone could give me a link to the bits I need to sort this out.

The phone was originally locked to tesco, but I'm on 3.

All help would be very gratefully appreciated.

Paul
