Whether you need a certain version of iOS, or a particular utility or program to jailbreak your iDevice, this section will certainly be helpful for whatever you seek.

Finally, comex has just released his new tool "JailbreakME " to Jailbreak iPhone 4 / 3GS New and Old Bootroms, iPod Touch 3G / 2G on iOS 4 / 4.0.1 and iPad on iOS 3.2.1, It's pretty simple and install is painless with one click! no need to enter DFU mode, no more issues and errors, more custom firmwares. This is the real fun!

Description in the Site:

Well, this post wasn't important but I think most of you thought that Semi-Spirit Jailbreak for iPhone 4 would be out at the end of this week? nope, you may need to read this post. I will talk about two points, the first is that the Jailbreak is delayed due to some issues in FaceTime and Multitasking, Second point is that most of you think it's "Spirit" but due to some sources, It's Not!

After Sn0wbreeze V1.6.2 has been released, and it came with fixes for Youtube issues and Itunes restore errors, Still some people getting errors while Restoring! they still can't restore using custom firmwares created by PwnageTool or Sn0wbreeze. So here's a new trick or a new way to jailbreak iOS 4 on iPhone 3GS but must be Jailbroken on 3.1.3 with Spirit Using Spirit2Pwn.
Note: If you haven't jailbreak yet, then you can Jailbreak your 3.1.3 using Spirit by the guide posted here. If you are already on iOS 4 (not Jailbroken) then you can downgrade back to 3.1.3 then Jailbreak using the same guide.

Steps:

Planetbeing, one of the iPhone Dev Team has just posted on his twitter account that it's possible to develop exploits that could work on the future and not only on the iOS 4. This Jailbreak tool may be Comex's tool "Spirit" which was updated to fix iTunes 9.2 from couple of days.

Yes, That's right. Spirit has been updated and brings support for iTunes 9.2, The new version is compatible with iTunes 9.2 and it Works only with iOS 3.1.3 and iOS 3.1.2 for iPhone, Also iOS 3.2 for iPad. But not yet for iOS 4 and iPhone 4.

Spirit jailbreak now available on the Linux OS, as we know that the Spirit jailbreak which has been released the last month is an iDevices jailbreak tool, the Spirit make a jailbreak for the iPhone 3.1.3, iPad 3.2 and iPod touch 2G/3G.

Wondering What's Jailbreak, and How it can be Done? you heard a lot about Jailbreaking and it seems like a dangerous process, Here's a guide for What you need about Jailbreaking any Device ..

MuscleNerd (one of the iPhone Dev-Team) posted some tweets for how to prevent Baseband update after Spirit jailbreak using a method called "last-ditch" for those who ignored warnings on SpiritJB.com to not use Spirit if you're using blacksn0w on an iPhone 3GS without 3.1.2 SHSH blobs on file.This is not a jailbreak or an unlock by itself. It's much safer (that method has the potential to brick your baseband if your timing is off).
Some People who were using blacksn0w on their iPhone 3GS at 3.1.2 tried to apply the Spirit JB without removing blackra1n. They found themselves in a reboot loop or stuck at the Apple or recovery screen.
