How to install Ultrasn0w unlock manually without internet connection

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Thankfully, we have solutions to install ultrasn0w manually as blogged earlier - however, the trick shared earlier is outdated now and UltraPusher is no longer updated.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.

Ultrasn0w Updated To v 1.2.2 Supporting Unlock For iOS 4.3.2

Ultrasn0w Carrier Unlock Updated To Work With Baseband Later Than 05.13.04

The most widely used iOS software unlock Ultrasn0w just got updated by parent iPhone Dev Team to support carrier-unlocking on any baseband later than 05.13.04 for iPhone3G/3GS owners. This unlock is interestingly using the exploited AT+XAPP command security-hole which was actually plugged-in by Apple but it turned out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 which is still vulnerable to AT+XAPP exploit and since the iPad baseband is built for the exact same baseband-chip as the iPhone3G/3GS what we have is an exploit with a carrier unlock for these devices. In simpler terms iPhone 3G/3Gs owners can unlock their devices running iOS 4.1/4.2 but there are some risks as posted next.

Unlocking iPhone Without Wi-Fi or Internet Connection

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.
