If you download the app from the itunes store it is very easy to setup. You only need to enter your primary email address and password.
There is no profile to install. Once installed on your phone you just need to enter your primary email address and password. When you are in range of a BTWifi hotspot it will log on automatically. If you go into the settings on the app you can set it to notify you by sound and vibrate once connected.
I use an Android phone and it works without a problem so I would imagine it will be the same on your iPhone.
