Glad to see unlocking worked for you. I will be trying it as soon as I buy my 'o2' Tab tomorrow. I was interested but did not understand your reference to 'dual sim'. Can you run dual sims on the Tab? I have copy a Iphone & Blackberry, both from China that work perfectly and I love their dual sim capacity.
