I want to install for testing an app on the iphone from a friend. The UDID I have registered on my developer account. What else should I do so that the installation work?
1. Add the UDID to the mobile provision and download the updated file (replace the existing one).
If you want to debug the app then you need to follow this tutorial: Installing B4i-Bridge and debugging first app
If you just want to run it then you can compile it in release mode, download the ipa and install it through iTunes.
