From iOS 7.0.2 the MAC address is: 02:00:00:00:00:00. How can I read real one in iOS? Is this unvailable from 7.0.2, or not? How do it?

This is a privacy change, so there's no way to get at the underlying MAC address. https://developer.apple.com/news/?id=8222013a
If your apps use the MAC address to identify an iOS device, the system will return the same static value for all devices running iOS 7. Please update your apps to use the identifierForVendor property of UIDevice. If you need an identifier for advertising purposes, use the advertisingIdentifier property of ASIdentifierManager.
