Absolutely Not.You can't upgrade an iphone 4 to iphone 4s!This is absolutely impossible!The iPhone 4s is an other created device from Apple wich as the A5 Chip,while iPhone 4 has the A4 Chip!
Not really as there is differences in the operating software and different hardware on bother versions of the iPhone.
The iPhone 5 is shaped differently than the iPhone 4, so the case would not work. It may fit, but it wouldn't be as snug as a fit as you would want. It is usually better to buy the case for your specific iPhone.
The iPhone 4 has reception issues and the iphone 3 dosn't
There are many differences between the iPhone 4 and the iPod Nano. The main difference is of course, the one you mentioned, that the IPhone obviously has phone service and the iPod Nano does not. Go to the nearest Apple store or to www.apple.com for a full feature list for both products.
