I've had my contract almost a year now and I've just got a new phone. I'm planning on trading my g1 in at cex, but they will give me an extra £20 if its unlocked. I've read somewhere that Tmobile will unlock your phone for free if you've been on the contract for atleast 90 days. But this might have been about Tmobile in the USA. Anyone know if its the same in the UK?
