Unlock iPhone: UltraSn0w 0.9 & Purplesn0w RC2 Released

Jailbreak iPhone 3GS using redsn0w on Mac

iPhone Dev Team has released an updated version of UltraSn0w 0.9, their software solution to unlock iPhone 3G and iPhone 3GS.

They believe that the new version "pretty much all of the various random issues that have been reported".

In the meanwhile, Geohot, the member of the iPhone Dev Team who had released his own software called purplera1n to jailbreak iPhone 3GS running iPhone OS 3.0 and couple of days back had released purlesn0w to unlock iPhone 3GS has also released purlesn0w RC2 which fixes many issues.

iPhone Dev Team believe that the new version "pretty much all of the various random issues that have been reported":

  • Works on both iPhone 3G and iPhone 3GS
  • Works on hacktivated devices
  • Works regardless of how you jailbroke your device
  • Doesn’t patch any mach-o binary whatsoever.  (Doesn’t require a separate patch as each new firmware comes out).
  • Doesn’t install any additional daemon
  • Has no race conditions, no popups about “Missing SIM”, no network issues
  • Is almost 7000 times smaller than its nearest competition :)
  • Is available now via Cydia.  Source repo is http://repo666.ultrasn0w.com (that last “0” in ultrasn0w is a zero!)

Geohot has released purplesn0w RC2 which has fixed the following issues:

  • Works on only iPhone 3GS
  • 3G(the network speed) issues fixed

  • Now only patches one file, CommCenter

  • Leaves no traces on your baseband after it runs. Seriously

  • Much more clean and reliable.

He has provided the following instructions to unlock iPhone 3GS:

  • Be sure to have legit activated 3GS

  • Disable 3G if you don't have it(like T-Mobile).

  • Add apt.geohot.com to Cydia

  • Install(or Update) com.geohot.purplesn0w

  • Watch for success output in Cydia(actually do this step)

  • Wait for signal, and enjoy your unlocked iPhone(no reboot required)

When Geohot had released his own software solution to unlock iPhone 3GS, he had claimed that his iPhone 3GS unlock solution is better than UltraSn0w. Dev Team have published details on their blog on why they don't agree with his claim to which Geohot has also responded on his blog.

So if you are planning to unlock your iPhone 3GS running iPhone OS 3.0 then you can try UltraSn0w (works on iPhone 3G as well) or purplesn0w to see which one works well. You can checkout our step-by-step guide to unlock iPhone 3G/iPhone 3GS running iPhone OS 3.0 using UltraSn0w.

Please don't forget to take a backup of your iPhone (refer to this post for more details) and also proceed with caution as it could void it's warranty.

Please tell us how it goes and which unlocking solution is better.

  • Mark

    I used purple rain "purplesn0w RC2" method to unlock my 3gs. To see if it working I took a t-mobile sim and put it inside the phone. I am unable to get any service and the phone is still " searching". Please advise me if there are any more steps I must take. Thank you.

    Another question, how do I get a data plan with T-Mobile that is compatible with the 3GS?

    PurpleSn0w did not work for me. UltraSn0w did great… still trying to see if it drains the battery

  • james

    if you already used ultrasnow can u just install this one on top of it?

  • http://profile.typepad.com/iphonehacks iPhoneHacks

    Yeah you can simply upgrade to the new version.

    If you have not observed any issues, you don't need to update.

  • Not-So Confused Guy Anymore

    Ultrasn0w worked perfectly for me.

    if we restore our jailbreak set and send to apple still can under warranty?

    Using the new Ultrasn0w on my 3GS with T-Mobile and it has been flawless. I highly recommend it.

  • toronto1

    Using the new Ultrasn0w on my 3GS with ROGERS and it has been flawless. I too highly recommend it. lol

    But seriously its been running great with no problems. No signal loss, no call fails, no nothing! Great job there Dev Team!

  • raymondleeus

    Just finished jailbreaking and unlocking 3GS using redsn0w and ultrasn0w.

    Now reinstalling/resyncing all my notes and contacts etc.

    For those who have problem of jailbreaking, try doing it on a different computer. For me and for unknown reason, consistently I couldn't do it (3G and 3GS) on another DELL though I could successfully do it on this DELL and a friend's MAC. Both DELL runs Windows XP SP2.

    Good Luck.

    Worked great with Ultrasn0w… Just took a minute for the T-Mobile logo to show up.

  • Nesto

    I recommend Ultrasnow because Dev has been out longer then purplesnow has, plus its more stable because they put there time and effort into fixing this file to make sure that it was good. Its obvious because they unlocked 3G. If anyone needs help with there phones feel free to email me LBNEC4Life@gmail.com I am more then willing to help out. I love my iphone and it works great im actually in germany right now using my unlocked stateside phone over here.

  • Vishnu

    That is correct but, the guy who made purplera1n used to be in the dev team
    I recommend purplera1n for jailbreak and also for unlocking

    Thank You
