Dev Team Says UltraSn0w Is Better Than PurpleSn0w

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 http://repo666.ultrasn0w.com (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 Releases PurlpleSn0w iPhone 3GS Unlock

A few days after releasing PurpleRa1n, the first iPhone 3GS jailbreak, GeoHot has now created his own iPhone 3GS unlock called PurpleSn0w.
Wifi fails? Battery fails? Unlock fails? You need purplesn0w, the geohot 3GS unlock solution. Now I know you here a lot about different colors of sn0w, but I’m here to tell you why purplesn0w is the best. First off, what is purplesn0w? It’s a soft unlock for your 3GS that I’d actually use day to day. It’s not a daemon that takes any resources, and it doesn’t add a task to your baseband. It’s very close to a true unlock. All it does is patch three files, CommCenter, lockdownd, and your wildcard activation plist(which you need, activate w at&t sim first, no hacktivation support yet).
Many users reported losing wifi connection and not being able to get any signal after unlocking their iPhone with UltraSn0w, so hopefully PurpleSn0w will get better feedback.

Follow these steps to install PurpleSn0w:

First your iPhone has to be jailbroken (see jailbreak guides)
Launch Cydia and add this source: http://apt.geohot.com
Install the com.geohot.purplesn0w package
Reboot your iPhone
Done!

If you want to unlock your iPhone for T-Mobile, make sure you disable 3G in the settings.

GeoHot also posted technical information about PurpleSn0w. If you’re into dissecting lines of codes, GeotHot made the source code available for you to play with.
