The friendly fight between the Dev Team and GeoHot keeps going as the Dev Team posted a blog post this morning highlighting how much better than PurpleSn0w UltraSn0w is.

  • Works on both 3G and 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 (that last “0” in ultrasn0w is a zero!)

That was the short version… If you want to full geeky version of this, head over the Dev Team’s blog. Although PurpleSn0w might not be perfect, the Dev Team used parts and pieces of GeoHot’s findings and included them in the latest UltraSn0w 0.9 update (available through Cydia).

What’s really better? UltraSn0w or PurpleSn0w?

Honestly, I don’t know. I don’t need to unlock my iPhone right now so I haven’t even tried any of these. If I had to pick one though, I’d choose UltraSn0w. I trust the Dev Team is doing what’s best for your iPhone now but also takes into account future updates that might render the unlock impossible. GeoHot on the other hand, seems to be a burning head.

Have you tried UltraSn0w and PurpleSn0w? If so, what do you think?

    GeoHot just release a new RC2 of purple snow.

    purplesn0w RC2
    * 3G(the network speed) issues fixed
    * Now only patches one file, CommCenter
    * Leaves no traces on your baseband after it runs. 0 bytes of RAM
    * Much more clean and reliable.

    Be sure to have legit activated 3GS
    Disable 3G if you don’t have it(like T-Mobile).
    Add 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)

    got that off his blog. I love the competition woo! haha

    I am reading both side’s explanations, Dev Team and GeoHot. I’m only a simpler user and i think Dev Team’s explanation that GeoHot’s 1MB memory exploit will eventually be corructed and crash the baseband coz memory is earmarked for specific use makes sense.

    Both blogs is a mess with many problems raised, i think some problems are only fabricated by loyal dev team or geohot fans, sorry.

    I dont know which is better. I am unlocked with ultrasnow on my 3g but my wifi keeps dropping. It will be on for a minute then disconnect, then reconnect. I dont understand. Does anyone know if this has to do with the ultrasnow unlock?

    • Well first, both these methods are unlocks so they have nothing to do with your iPhone being jailbroken or not. Second, I can’t tell you why your iPhone is not jailbroken. I wrote very simple tutorials on how to jailbreak your iPhone. I suggest you have a look at it 🙂

    I used Geohots purplesn0w RC2 a couple days ago and I must say it was very easy to use. This was my first time jailbreaking my phone and I am very happy with the results. No disrepect to the dev team, but I heard geohots version was easier to install so, I went with that.

    All the expert of iPhone out there, I need some help & advised. I have updated my iTune to and my 3G iPhone to 3.0.1. I using redsn0w v0.8 to jailbreak today’s 3.0.1 update. Then run redsn0w and point it at the 3.0 IPSW instead of the 3.0.1 one. all went well.
    Then I went to Cydia to add in the souce and install ultrasn0w. Now i should be able to add any IPA file to work, but is not.
