Gyroscope available since Feb 2010. Want some spares?
http://www.st.com/stonline/products/lite...
ST released this gyroscope last February. The PDF is their product brochure on it. Unlike what you spew as some wonderful Apple-only invention, as usual, anyone can buy them from their electronics wholesalers worldwide since Feb 2010....even Apple.
This wasn't built for Apple. It's off-the-shelf parts. Check the revision history at the back of this document.
Is this a good question?
