The previous summer releases wil be pushed back to fall ones
Apple will release the new iPhone 5 and all new iPhones in fall, discarding the previous summer cycle releases.
All iPhones except the iPhone 4S were released on summer. We though that this iPhone 4S release was an exception but it wasn't, it was the first indicator of the new Apple's release cycle for this product to be released in fall every year. So, the new iPhone 5 will reach us after the summer for sure.
