We just deployed a major update for the Apple iPhone/iPod Touch XBOX Live Friends List. With this update, we've eliminated the need to enter all of your friends into one big text field. The new "Preferences" interface allows you to manage the gamertags as a list. You can now update, delete, and even re-order your friends. With this new version, you can even update your existing friends list by clicking on "EDIT LIST".
If you already use the 1337pwn application, you'll get this functionality automatically. For new users, simply follow the link below.
Thank you for the great feedback and support.
