Re: [iPAQ] iPAQ 3650 headphone jack modified to accomodate microphone input

Hi,

Last night I successfully modified the headphone jack circuit on a
iPaq 3650 so that it can be used for microphone input as well. I'm
using a Jabra EarWrap (see http://www.jabra.com/products/mobile.htm)
with it and everything seems to work well.

One problem is that the internal microphone has been left
disconnected. Another is that the headphone output is not now mono
but right-channel only. I'd like to fix this but would be helped with
a bit more information. Are schematics or scans of the circuit board
available anywhere?

Thanks in advance,

That is so cool. Did you take pictures? How did you fit in the longer
jack?
