I'm on Vodafone so, like many many others, still eagerly awaiting the illusive unloock. As a temporary measure, I'm thinking of going for an O2 Pay As You Go SIM just so I can use the damn phone. Have many others on here gone down that route? Is it reccomended and/or easy enough to do? I've activated and downgraded to 1.1.1, where I've left it for the time being.
