Here is what you do to get it working: Works on mine...
Uninstall everything FoxFi, the key the app
Go to Settings-Security-Trusted Certs, User at top and delete the FoxFi cert
reinstall FoxFi and Key
It will ask to install cert, yes
It may ask for VPN install, yes
You 'may' need to use a lockscreen lock to get it to work, don't know. I am using the number input for mine
Start and run FoxFi, set it up like ya like and wala! No having to hit home button anymore either!
Let me know how it works for ya....
