pinout jack Motorola i830

[FloJoe]

Hello everybody,

we have to change our headset and have to do it ourselves, so I took a usual headset for the i830 and looket at the pinout of teh 2.5mm jack, what I think is the following:

from TIP to cable:

1) MIC
2) GND
3) Speaker
4) PTT

Can anybody confirm this????
Please need urgent help and there is just no pinout about this jack in the internet. Ridicules! THX

no that's not right.

The Motorola i830 has the following 4pin pinout (pin 1 is the tip):

1) MIC+
2) SP+
3) GND
4) PTT
