What you are describing however, is currently impossible. You see, Apple has created what is called a "Sandbox" with its iOS environment. Essentially this means that if you do not work for Apple, all your app gets is one tiny room in the operating system, with no access to management.
Put another way, Safari will always be the default browser on any iOS device, and until Apple decides to change their mind about that, it is not possible for us to be the default way to open links.
The same goes for ANY browser that you install onto an iOS device. Long story short, if you really want CE to be able to be the default browser (and we think that would be awesome) the people you need to talk to, is Apple.
As a side note, we did make improvements to opening free wifi screens, and more of those are coming.
