The 30-pin dock used on almost all of the range for Apple iPhone, iPad and iPod looks set to be ditched in favour of a new 19-pin connector, according to reports from Reuters.The smaller connector is part of efforts to move the earphone to the bottom, two sources told the news agency. The new connector would be incompatible with existing docks and would mean that iPhone 5 users would have to buy brand new accessories in order for the iPhone.

Analysts told Reuters that this would mean new business for accessories makers.

Pete Cunningham, analyst at technology research firm Canalys told Reuters that : “The iPhone connector has been a standard for a long time now and I would expect the same to be true for a new connector, should Apple change it as expected.”

Some Chinese vendors are already offering cases for the new iPhone sporting the smaller charging pin and the earphone socket on the bottom, along with “guarantees” that dimensions are correct.

The 30-pin connector has been in use by Apple since the third generation iPod came out. It is expected that alongside the connector, a new adaptor would be sold alongside to maintain compatibility with existing docks.

As reported on Absolute Gadget, the new iPhone 5 is expected to launch on 7 August.
