Support New to smartphones, bought international s3 unlocked by Orange

view story

http://androidforums.com – The version that I received seems to be an unlocked version from Orange, some french provider (I didn't even receive an English manual) . My phone settings were in French but I reset everything and I get the Orange splash screen, and some icons like the web browser is orange, and there are also some pre-installed orange apps... Is it possible for me to reset everything basically to make my phone have no association with Orange? I still need it unlocked... Thanks (General)
