Typical, had my N70 for 18months, faultless, sell it, 2 days later the mic is no longer working.
Anyway, had it sent back and sure enough no mic. I plugged in the headset and that mic, via the pop port, works fine.

Does this rule in the inbuilt mic as the problem rather than elsewhere in the phone ?
I'm not sure where the inbuilt mic and pop port mic merge in the cct.
I've checked the internal mic connection for issues but it was fine.

Where can I get an internal mic post haste to test it ?
Thanks
