Earlier, the redsn0w jailbreak used hacktivation procedure to activate your device without the original SIM card. This would enable the phone to operate and unlock, however the iPhone would keep sending the certificates for the original carrier over Wi-Fi or 3G that drastically reduced battery life and eats a lot of bandwidth. This hack would also solve the Push Notifications issue and all the applications including YouTube would work perfectly.
