I'm days away from the end of my O2 contract and I've sent in my unlocking request. The intention in due course is for her indoors to have the 3G on a new PAYG arrangement and for me to get a 3GS on contract, probably not with O2. I presume she will then sync the 3G on her laptop - but how does the laptop know it's Mrs Flaneur's phone now? How do I make sure that she doesn't get all of my apps? Sorry. Noob questions.
