According to several patent applications, Apple is planning on making the iPod touch thinner than the headphone jack you plug into it.

In the patents (above), Apple outlines three ways this could be made possible. The first (left) involves an audio socket that isn’t quite a full circle – allowing part of the jack to protrude out of the socket. The second (center) involves a socket covered with a flexible material – when you insert the audio jack, the material expands. And, the third method (right) involves a couple of little doors that swing open when a jack is inserted.

Most of us – including myself – probably thought the depth of Apple’s iPod touch was limited by the audio socket it has to house. Unbelievably, it looks as if Apple has a few ways they can get around this limitation.

We’ll keep you posted.
