Ad hoc distribution provisioning profiles will not enable you to sign any code. Instead, it allows you to install and run a particular app (or a handfull of apps, depending on the settings) signed for ad hoc distribution. The profile specifies which devices the app may be run on. You are going to import the profile and the app to iTunes and sync your iPhone to use it.

The advantage of ad hoc distribution is that you do not need to publish an app to the AppStore to distribute it, so you can quickly test minor changes on some beta tester devices. You may use this way to distribute the app to up to 100 unique devices per year. One downside is of course that Apple cannot take care of updating and distributing your app. You have to do that manually. Furthermore, you are restricted to the 100 devices and you cannot sell your app.
