I wonder if someone can help me... I will soon be eligible for an upgrade on my existing O2 contract, and already have an iPhone 4s. I would like to get the O2 on and on tariff, but obviously don't need another iPhone However, I would like to get a new blackberry torch to use with my corporate sim (I have an old blackberry storm at present, which has the worst touch screen in history!) Could I get a new 'blackberry' on and on tariff, to get the free blackberry torch, and then switch it to an iPhone tariff for the data straight away? Many thanks.
