As previously reported, Apple is going to replace the iconic, and sometimes frustrating, 30-pin dock connector with a new miniaturized version. Originally it was thought that the new connector would be added to devices as they were updated according to the usual update schedule. However, Apple is said to be updating the entire line-up with the new connector this fall.
This update will include a 9.7-inch iPad, as well as the next iPhone, the iPod Nano and touch, and a possible iPad mini. This means that the current iPad 3 will be updated with the smaller connector mid-season. Of course, updating all of the devices at once makes sense. Otherwise half of the devices would be using the old cord, and half the new cord.
Unfortunately, this new connector could make older accessories incompatible. They are making an adapter, however, it may not work with every device. A major example comes to mind: Car integration. The iPhone is said to be announced on September 12 and launched on September 21 and the rest of the updated line-up is likely to come at the same time.
