The life cycle of Apple could be late summer or very early fall. The invitations from Apple generally go out the week before the event, and this is usually on a Tuesday or Wednesday. IOS 7 could be revealed at the same time and pre-orders for the device could start on the Friday. ISO 7 could be then available for download on the same day.
It has been said that the Apple iPhone 6 may have the quad core processor and this would be faster than the processor of the iPhone 5. If so it would work great with iOS 7 as iOS 7 comes with many new features.
It’s also been said that the iPhone 6 may be coming choices of 16 GB, 32 GB, 64 GB and 128 GB.
