If you have an Apple iPhone without a working WiFi connection and you are dependent on the Ultrasn0w software unlock, you are stuck in a sort of classic "Chicken or the egg" dilemma - you dont have an WiFi internet connection and you can't use your cellular data network until you unlock your phone by first downloading ultrasn0w via Cydia !!!

Thankfully, we have solutions to install ultrasn0w manually as blogged earlier - however, the trick shared earlier is outdated now and UltraPusher is no longer updated. We can still get things done manually as instructed ahead.

If you have Wi-Fi or internet connectivity on your iPhone it's pretty easy to install carrier unlock Ultrasn0w via Cydia on your device, however, things get complicated if you have no internet or Wi-Fi available on your iPhone leaving you with no choice but to install Ultrasn0w manually which require working with iPhone file-system and file-permissions.

Thankfully, we do have a pretty much unknown utility 'UltraPusher' which lets users install MobileSubstrate and Ultrasn0w on their iPhone offline from any windows computer, all you need to do is to connect your phone via USB and let UltraPusher inject the required files automatically.
