IPhone 4 mic malfunction after iOS update?

The mic worked perfectly. I didn't drop it or damage it. I updated to the latest iOS 6.0.1 and tried taking a call the day after. But the person who receives the call can't hear me. But I can hear him. I thought the mic had broken but I tried voice memos it worked fine perfect sound quality. Then I tried video recording it worked perfectly too. I tried calling one viber and Skype they work perfectly too. But only GSM calls can't be taken. Can someone please help me with this. My friends say its a bug in the iOS and it will be fixed in the next update. But I can't wait much longer. Can someone please help me with this.

Is it just that person or is it when you call other people too if its just that person it's their phone if its everyone then it is yours take it to apple they should be able to fix that

Try restarting your phone. That usually corrects minor bugs. If it problem persists then restore your phone. If that doesn't work then take it to an Apple store and get it checked or replaced (if its still under warranty).

My music is still on my itunes in my laptop, but when I go to my iphone tab it says there's no data, and it won't let me hit the sync button and it's not telling me why. I tried restarting my computer and that didn't work. I hit restore but I'm afraid to do it since it says it will erase everything on your phone.
