We have detected an issue at Salesforce SDK 4.1.0 for hybrid applications (in our case local instead of remote) on Android 6 platform. When the application is launched the first time, the back button doesn´t work. After closing and opening again, it works correctly. On Android 5 it doesn't happen.

We would like to include on our hybrid local application developed for Android 5.0+ and IOS 8+ a back button for the salesforce login page. Instead of launching this page at the start, we are opening on a specific point, so its neccesary to manage this event. 
In Android we have achieved it by modifying the fixBackButtonBehavior method at LoginActivity. However in IOS, we can't change the classes because they are .a files. 
How could it be done? Is possible to do without changing native code?
We are using the 4.1.0 SDK's version.

Hi,

We are looking to enhance security of our mobile applications that integrate with Salesforce iOS and Android SDKs. How do we implement certificate pinning so that man-in-the-middle attacks are prevented? The Salesforce SDK uses an internal HTTPS connection, which are not accessible for inserting the check for Salesforce Certificate.

Any help would be much appreciated.
