Among the most circulated rumors on the new iPhone lately has been that Apple will drop the 30-pin connector it has used on all its portable devices since 2003 for a smaller 19-pin connector.
This has inspired Apple critics to jab at Apple fanboys who have tolerated the expensive proprietary cables and connectors while most of the rest of the mobile world shares micro USB. Those who own a number of 30-pin iOS accessories that possibly face obsolescence couldn't be faulted for telling Apple where they can stick their new connector. But reportedly Apple is coming out with an adapter. While plausible this solution seems awkward and highly un-Apple.
Why has Apple rebuffed the industry standard micro USB? By implementing its own proprietary 30-pin connector, Apple has been able to exercise more control over accessories and cash in on "Made for iPod" licensing.
Reports also say that Apple is expected to move the headphone audio jack to the bottom like on the iPod touch. Well, at least it isn't on the side.
Cult of Mac has pretty good explanation of Apple's connector shell game.
