I don't know if your assessment is 100% correct. I am on BES but they have turned off MDS on the BES. This means, even though I have two browsers, I can only use the one from my carrier (TMO) to surf or 3rd party apps. It was my understanding if you have two browsers (BES and carrier) you really have both configs in your picture.

Now let me try and answer what I can for you....

Yes, except number 3 is usually selectable, you can set your default in browser settings which will stear the default data to either BES/MDS or BIS. Hopefully, the 3rd party app creator will make this selectable. You must also keep in mind your BES admin can control/limit this via the policy.

...How does carrier force Internet browser to skip Corp BES?.
See the picture you found, it shows the path of each browser... It must be your BES that is limiting access. Remember, the BES can only limit your carriers TCP via a policy to your device. That limitation is mostly on or off.

If you use the BES browser then yes, if you use the carriers browser no.

No, the policy cripples the ability of the phone itself so if the policy lets you make calls, even if the BES is down, you can still make a call or SMS.

Welcome to the world of BB...
