How to unlock iPhone 3GS on iOS 5 and 5.0.1


If you’ve updated your iPhone 3GS to iOS 5 or 5.0.1 and lost your unlock we can help you get it back. The actual jailbreak will be tethered but you’ll still be able to unlock and continue using your device in the mean time until an untethered jailbreak solution is released. iPhone 4 and iPhone 4S users should steer clear of this as it will not work.

Devices supported

  • iPhone 3GS

What you’ll need

  • RedSn0w 0.9.9b5 or later, we recommend the most current version which is RedSn0w 0.9.9b8 – Mac Link, Windows Link
  • A working SIM card (doesn’t matter what carrier as long as it’s activated and working)

Jailbreak with RedSn0w and Install the iPad baseband

You’ll follow the same steps are you would to jailbreak via Redsn0w except for one difference. Instead of just checking Install Cydia you’ll need to check offInstall iPad baseband. RedSn0w will warn you that this can not be undone. Agree and continue the jailbreak process.

Boot Tethered

After jailbreaking you’ll need to perform one tethered boot before unlocking. Simply launch RedSn0w again and click Extras. Check the box for Just boot tethered right now. You’ll be walked through DFU mode and your phone should reboot.

Install UltraSn0w

After your phone reboots you’ll need to perform the following steps to unlock it:
  • Open Cydia and search for ultrasn0w
  • Install the ultrasn0w package to your device.
  • After installation is complete your phone should automatically ask you to reboot it. If it doesn’t, reboot it manually.
  • You’ll need to jump into RedSn0w one more time and perform a tethered boot like you did above.
  • Your phone should now be unlocked. It may say Searching… for a few minutes before finally connecting to the network.

    • Known Issues

    A few users have seen issues where their phone will not obtain service after using ultrasn0w on iOS 5 or iOS 5.0.1. If you have this issue, launch RedSn0w once more and choose jailbreak again. Instead of going through the whole process this time, you only want to check Deactivate. Do one more tethered boot and you should be good to go!

      Actual escape will be bound, but you can still unlock and continue to use your equipment, the average time until unrestricted escape solution is released.

    Ipad 2 Accesories

    By
    Zagg have done it again and released what we are excited to say is the seasons MUST HAVE iPad accessory: The  ZAGGmate iPad case with keyboard . It’s not often that we get entirely blown away by an accessory for the iPad, but this one has left us shell shocked and in awe. The perfect compliment to your iPad, this is the first iPad keyboard case combo that we have seen yet that has done it right. In fact, it’s the best bluetooth keyboard we’ve seen to date as well! It’s so right and so perfect that we already wonder how we ever used our iPad without it! Check out the review below… ZAGGmate with Keyboard The iPad’s New Best Friend Our first impression of the ZAGGmate was: “Where’s the rest of it?” This iPad case is unlike anything else we’ve seen on the market to date and the designers at Zagg worked hard to literally rethink what an iPad case could be. This is an iPad case that doesn’t cover the whole iPad, but rather just covers the iPad’s screen, and leaves the back of the tablet...

    Ipad 2 Apps: Skyfire Web browser Review

    By
    Ipad 2 Apps: Skyfire Web browser Review Skyfire for the iPad made headlines when it was first released, due to its ability to play Flash videos on a device previously void of this popular technology. Users flocked to the App Store, eager to drop five bucks for the chance to view their favorite clips, shows, and movies on their iPad. Not only did the browser play these videos, but the integrated video compression saved a significant amount of bandwidth for people on a restricted data plan. The initial excitement wore off quickly, though, as complaints were rampant about many sites not playing videos as expected. Since its inception Skyfire has certainly improved in this area, now claiming support for over 200,000 websites containing Flash. The dissenters will always be there as not every Flash video on the Web will be playable, even if the developers at Skype Labs remain diligent. Some of the backlash is warranted to a certain extent. If I paid $4.99 with the intent of viewi...
