iPhone 1: 4GB & 8GB... eventually released a 16GB in February iPhone 3G: 8GB & 16GB iPhone 3GS: 16GB & 32GB iPhone 4: 16GB & 32GB iPhone 4S: 16GB, 32GB, and 64GB iPhone 5: 32GB and 64GB??? The first couple years of the iPhone the storage would steadily increase with each passing year, but then it sort of plateaued on the 16gb & 32gb sizes. Although Apple finally did add a 64GB model last year (for a $100 premium). Now with all the high res pictures it takes and 1080p video, along with all the power intensive, retina quality games and apps, we need more storage on our iPhones than ever. So I'm hoping that Apple increases the base model iPhone to 32GB. Then the iPhone 4S can be 16GB sold at $100 and the iPhone 4 at 8GB of course costing $0 on contract. Maybe this is just wishful thinking. What do you think Apple will do?
