Unlocking iPhone means hacking the iPhone to make it work with other network carriers. One need to have internet or Wi-Fi connectivity in order to install iPhone unlocker such as Ultrasn0w and unlock the device via Cydia. But problems arise when you don’t have either Wi-Fi or internet connection available on your iPhone. If this is the case with you, you need to install Ultrasn0w offline, which is a bit complicated as it requires the access to iPhone file-system and file-permissions.
If you don’t have access to Wi-Fi or internet connectivity on your iPhone, you may proceed to unlock the device by installing a utility called UltraPusher. UltraPusher allows a iPhone user to install MobileSubstrate and Ultrasn0w offline using any Windows based system. Simply connect your iPhone with the system using a USB cable so that UltraPusher can inject required files automatically.
