I have just a general question here. If one purchases an iPhone outside the USA suppose in Europe, can the battery be replaced there or the phone MUST be shipped to the USA (or to China) in order for the battery to be replaced? I am in Europe myself, and I searched around and there are many Authorized Apple service shops in my area. But my question is, I purchased my iPhone here in Europe, but does this mean if I take to my local Apple service shop here in Europe, will the shop ship my phone to the USA in order to have battery replaced? And my next question is (sort of unrelated), how long do iPhone batteries last before the battery needs to be replaced? I am thinking that by the time the battery needs to be replaced, I will be buying my next phone.
