Ok, so we have had a bunch of trouble with testers trying to install iPhone apps using the ad hoc system. You’re supposed to use iTunes, and it works (sometimes) but strange things have happened for a couple of our testers. The apps gets installed and all, but it wont launch on the phone. This probably has something to do with the mobile provisioning files being updated wrong or maybe all files aren’t deleted from a previous installation when reinstalling an app.

Anyway, the solution was to use the iPhone Configuration Utility instead. Apparently, it’s a tool released to make life easier for large companies managing lots of phones, but it’s free and works fine for individual users as well. It’s available here.
