Right now we are developing an iPhone app for one of the BootstrapLabs companies. It is a social service, and right now we are starting to roll-out pre-alpha testing.
The ad-hoc distribution has always been a pain for Apple’s iPhone, and each tester had to be pre-registered and sync through iTunes on the Computer.

This time we decided we wanted to test something new and gave TestFlightApp (https://testflightapp.com/), and so far it seem to work great.

It is just as easy as upload the .IAP file, enter e-mail addresses and send them out. The user will then automatically register any mobile provisioning profiles just as before, but it is much easier for the user. The user then needs to register the development profile, but it can all be done from the iPhone, no need to connect the phone to iTunes.
