Change the carrier string in the iOS Simulator

carrier.py

# This script changes the Carrier string in the iPhone simulator
# to anything you want. It needs python3, and currently works when
# your Simulator is set to English. For other languages, change the
# 'language_code' variable to your language.
#
# This works for Xcode 7 and iOS 9, I havent tested on anything else.
#
# Usage: 'python3 carrier.py new_carrier'
