# new features:
# 1. change the app display name
# 2. change the bundle identifier by reading it from the provisioning profile. This means that

The cp on line 124 fails for me because of file permissions. You may want to add a chmod there.

cp "$NEW_PROVISION" "temp/Payload/$APP_NAME/embedded.mobileprovision

Nice work. Although your awking on line #107 isnt robust and assumes too much info about the app id.

I forked and learned awk and updated it: https://gist.github.com/3881230
