Help needed!! OSC remote

Could someone please post a tutorial or instructions (FULL INSTRUCTIONS!!!) on how to get the Hog template into the OSC iPhone app?!?!
I know the template is available for download on the HES website, but it is only a zip file...and it can't be opened from my phone.
I also understand that I need to point my app to the template, but I have no idea how.
Can't believe there aren't instructions yet (for someone who ISN'T a computer genius).
Any help would be appreciated!! Cheers!
