Mic on iPhone 4 doesn't work

[hackneyzoo]

That's it really. I can hear other people but when I talk they can't here me. Any way to fix this ?

Take it to a repair shop?

It seems to be a common fault actually - the mic at the top rather than the one at the bottom. Mine went a month or so back but fixed itself

This happened to mine last week too. Ended up taking to a friend who fixes phones and he changed it for me.
