Is there any free way of unlocking my SE T700?
 

A friend of mine from Britain sent me her old phone, a T700. My K850 is acting up, so I'd like to have this as a back-up phone for when (not if, when) my k850 finally kicks the bucket.

However...she thought that it was unlocked, but it's not. I downloaded AERIX, but it didn't work. I'm not sure if it matters or not, but it's a SIM card phone locked to Britain's O2 network. I'm with Rogers.

Any other ideas? I don't really want to spend much on it (if anything), it would really just be a backup phone in case my k850 decides to throw in the towel.

Thanks
