What is more likely, however, is a smaller, more condensed 30-pin port for the iPhone, as Apple continues its quest to squeeze even more out of the device size specifications. Apple could replace the standard and existing 30-pin connector with one that allows data and charging at current data transfer rates but smaller in width, making way for more hardware goodness.
This would of course mean that Apple would have to ditch its current lineup for new customers and build a whole range of new accessories, docks and connectors, and it would leave third-party accessory makers out in the lurch for a while. But it would give Apple more space to wedge in a slightly larger battery -- say to provide an equal and matching battery life of the iPhone 4S but while enabling power-hungry 4G LTE networking to run?
