IPhone 4S mic problem in the first seconds of an cellular call

   Hi, I bought a brand new Iphone 4S ( iOS 6.0.1 ) from Apple Store 2 weeks ago. In the first few days everything seems to work fine and then one morning people could not hear me very well on the phone ( using the apple headsets everything worked fine ). 1h later I got the Iphone working back suddenly but I got a new issue which I have it even now. In the first 2 sec of cellular call ( incoming or outgoing ) I can't be heard; after this 2 sec everything it's ok and I can be heard. This issue is not reproducible on Facetime, Viber or by using other type of applications.
I don't think this can be fixed by restoring the IPhone but I do think that is an iOS bug. Please let me know if you ever encounter this issue.

My iphone 4 does exactly the same, there is a Youtube video about putting a piece of card under the back cover in a strategic place to resolve this.
