Um no, it is installing just Installer! I mean it even patches the TIFF exploit for you!. If you want to check for "who knows what else it is installing" just SSH to your phone and check.That's what scares me. Who knows what else it's installing. It's like pulling your pants down and inviting someone to.... well, you know.
After unlocking, you go to the "Unlocking Tools" section in Installer that you added to install anySIM and there are some certificates for youtube. I installed them and youtube now works perfectly.what about youtube? as far as I now if you unlock iphone using jailbreakme, youtube won't works. Is there any way to fix it?
