Hi all, I am going to buy an iPhone 3G for nostalgia sake. Unfortunately, the battery on it, according to the seller, is really poor - it lasts maybe an hour they say. Therefore, I am going to get the battery replaced. Apple will replace it for £55 + £7.44 shipping (I am going to send it in). This seems like a fair price. This will result in me being sent a refurbished phone. However, the iPhone has a cracked display. Will Apple charge me for this, despite the battery in no way being affected by the display?
