Hi. I've been trying to do this via unlockforfree or whatever and I keep tripping up on the bit when they ask for the GEN: New Griffin etc. I have no idea as I haven't got the box. Can someone give me a code to unlock without this info? My IMEI no. is 356644/00/644963/6 and I want to change from Vodaphone UK to VIrgin UK. Any help gratefully received! Thank you.
