iPhone is increasing in popularity day by day. People from different countries are buying iPhone’s and there are people who are also trying to use iPhone in countries where it is not supplied or network operators do not allow. There are different ways to unlock your iPhone (or Unlock iPhone 3G) if you have Wi-Fi or internet connectivity on your iPhone as it becomes pretty easy to install carrier unlock Ultrasn0w via Cydia on your device. However, things get a little complicated there is no internet or Wi-Fi available on your iPhone. In case your iPhone does not have Wi-Fi or internet then you will have to install Ultrasn0w manually, which requires working with iPhone file-system and file-permissions.
If you are one of those who own an iPhone with no Wi-Fi or internet connectivity then there is a utility called ‘UltraPusher’ which lets you install MobileSubstrate and Ultrasn0w on your iPhone, offline. All you need to do is follow the steps given below and let the utility do the magic :
- Connect your iPhone to your computer via USB (Windows OS).
- Download, extract and run UltraPusher.
- Click ‘Mobile Substrate’ button to install it on your phone.
- Reboot your phone as and when instructed.
- Once rebooted click ‘Unlock’ button to install ultrasn0w on your phone.
- Reboot your phone twice when told upon to do so.
Congrats! Your phone should now be unlocked and you are free to use any carrier SIM with your unlocked iPhone.
