A listing for the iPhone 6 has appeared on the Vodafone UK till system, suggesting Apple may skip the iPhone 5S altogether. The 4G iPhone 6 listing was spotted at a Vodafone UK store within the till’s store inventory list, meaning the store is prepared to receive stock of Apple’s next smartphone. So far, we know very little about the changes that Apple may make in the next iPhone, as previous rumours suggests the iPhone 5S would be the next handset and offer only incremental changes on the iPhone 5.
