No, what is more probable is that the hardware was different enough to need to change it. iPhone3g and iPhone 3GS had different hardware and software that some apps Bly worked for the 3GS. Going to the iPhone 4 had retina display which makes a big difference. iPad 2 had 2 cameras and FaceTime which changed the experience of the device. The mistake they made wih the ipad3 was that it came we a better display and that is what people wanted but they didn't signify he difference in the product name. The reason this wasn't as important for the MacBooks is your everyday layman end user couldn't tell large differences between iterations other than body style which doesn't really change its capability all that much. Apple doesn't emphasize mobile specs so those differences wouldn't stand out as much as hardware and feature set.
