Famous hacker Geohot is back and today he released the latest iOS 4.1 jailbreak. It is called LimeRa1n and supports iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G with iOS firmwares 4.0-4.1 and beyond. It can also hacktivate your device, so there is no need in phone SIM-cards and other tricks.
This software is still in beta and was updated 3 times in last several hours. So use with caution.
There is Windows version only for now. Geohot plans to release LimeRa1n for Mac and Linux soon. You can Download it here.
Some users report that they have jailbroken their iOS 3.2.2 iPads successfully with limera1n, while others report that they tried, but failed.
Do not forget to backup.
For many users of iPhone 3GS and iPhone 4 with iOS 4.0.2 now there is a hope to perform jailbreak using LimeRa1n and unlock using ultrasn0w. We recommend NOT to do it if you have not saved your SHSH keys. You can try, but if something goes wrong without SHSH keys you’ll have to restore to iOS 4.1, and there is no unlock for iOS 4.1 (possibly forever). Just wait for PwnageTool utility.
DevTeam reported that Limera1n uses a different exploit than SHAtter, so they will not release SHAtter utility, they don’t want let Apple fix both security holes. However they plan to release PwnageTool using the same exploit.
DevTeam just released PwnageTool 3.1.4. It allows users to jailbreak firmware 3.1.2 on iPhone 2G/3G/3GS and iPod Touch 1G/2G. It also supports OTB iPhone 3GS with firmware 3.1.x. We remind you that if you need unlock, do not update on regular 3.1.x firmware, use Pwnagetool to create custom firmware to preserve old baseband.
Here is a quick howto:
Factory Unlocked iPhone 3G and iPhone 3GS: You do not need unlock, just use PwnageTool to create an ipsw and then use this to update and jailbreak your phone.
iPhone 3G and iPhone 3GS: if you need unlock, use PwnageTool to create a custom firmware with an old baseband. Then update using created custom firmware and install ultrasw0w via Cydia to unlock.
iPhone 2G: Use PwnageTool to do the magic and then restore with iTunes using your newly created .ipsw.The baseband will be unlocked, the phone jailbroken.
iPod Touch 1G: Use PwnageTool to create a firmware image and restore with that .ipsw using iTunes.
iPod Touch 2G: You must already be jailbroken in order to use PwnageTool. If so, create a firmware image and restore with that .ipsw using iTunes.
