Disabling web security, while not recommended for most apps, shouldn’t stop you from being accepted into BlackBerry World. It can be dangerous in the wrong hands, which is why the warning. Let me know if you have trouble with this after you submit.
Why do you need to get the wifi ip? It is trivial to expose the Native functions to WebWorks as an extension if you need it though.
I am excited to try this out, I appreciate you putting the effort into getting it working.

edit: This plugin allows you to get the wifi IP 🙂 https://github.com/blackberry/WebWorks-Community-APIs/tree/master/BB10-Cordova/deviceInfo
