Ultrasn0w 0.9 iPhone 3G/3GS Unlock Released

Earlier this week, Ultrasn0w 0.9 was released by the iPhone Dev Team. Ultrasn0w is the Dev Team’s iPhone 3G/3GS unlock solution.


The new update to 0.9 added a few enhancements to the Ultrasn0w package and fixed many problems that people may have experienced while using Ultrasn0w to unlock their iPhone 3G or iPhone 3GS.

Below is a brief list of enhancements for Ultrasn0w 0.9:

  • Works with both iPhone 3G and iPhone 3GS
  • Works with ‘hacktivated’ iPhones
  • Works regardless of how you jailbroke or hacked your iPhone
  • Does not require a separate patch as each new firmware is released
  • Does not install any additional daemon
  • No network issues, no pop-ups about “Missing SIM” and no race conditions
  • Almost 7000 times smaller than its nearest competition (Ultrasn0w wins again)

If you are still having some kind of issue with Ultrasn0w, below is a brief list of general tips for anyone that is still having problems:

Issue 1

Unusual battery depletion is usually caused by people choosing to “Restore from backup” instead of “Set up a new iPhone” in iTunes. This is not a cause of the Jailbreak or Unlock.

Fix 1

Redo the official 3.0 restore and choose “Set up a new iPhone” when iTunes prompts you. Your media will still be synced, but you will erase any conflicting Bluetooth, WiFi, or Carrier settings. Also, any SMS messages or photos on the camera roll that you wanted saved will be lost. Just remember, the “Set up a new iPhone” option will set up your iPhone as a factory fresh device.

Issue 2

Ultrasn0w works with ‘hacktivated’ iPhones as well, but do not outsmart redsn0w into thinking that you do not need ‘hacktivation’.

Fix 2

If you do not plan on using an official SIM card (Rogers, Fido) , do not activate your iPhone via iTunes with the official SIM. Instead, keep your unofficial SIM card at all times and let redsn0w and ultrasn0w handle ‘hacktivatation’.

Issue 3

T-Mobile in the USA does not use the 3G frequencies that iPhones support.

Fix 3

Turn off 3G on your iPhone 3G/3GS by navigating to Settings > General > Network.

Issue 4

Some unofficial plans have limitations on making calls and using data at the same time.

Fix 4

This is not unlock related.

Issue 5

Some users may have installed previous versions of ultrasn0w using non-standard techniques.

Fix 5

In most cases when installed, the updated ultrasn0w 0.9 removes all previous versions of ultrasn0w. If not, you can be sure by checking if /usr/bin/ultrasn0w is present. If the path is not there, then ultrasn0w 0.9 removed it successfully.

Issue 6

You do not want/need to update to ultrasn0w 0.9 from the previous version and you want to get rid of the red update badge that is on the Cydia icon.

Fix 6

You can remove the red badge over the Cydia icon by removing the repo666 as a Cydia source. If you remove it, you can always put it back and removing it does not uninstall your version of ultrasn0w.
