[ Working ] iPhone 4.0 Beta Jailbreak On iPhone 3G With Redsn0w 0.9.5 beta

by abhishek bhatnagar on April 16, 2010

iPhone Dev Team has just updated redsn0w to 0.9.5 beta to jailbreak iphone OS 4.0, however this tool works on iphone 3g only with 4.0 beta firmware. This new beta version of redsn0w is been released now only for Mac but windows version will be coming soon.


Note: Both the iphone 4.0 beta firmware and Redsn0w 0.9.5 beta are not meant for normal users as they might not able to unlock their phone after upgrading to iphone 4.0 beta firmware, so better stay away from both of these and wait for the iphone 4.0 firmware final release.

iPhone 4.0 Jailbreak Important Things To Be Kept In Mind

  • Redsn0w 0.9.5 BETA supports only iPhone 3G (atleast for now) and requires Mac OS X.
  • You should be a registered Apple developer or your iPhone UDID should be registered with any iPhone Dev, so you can install the beta version.
  • If you update to OS 4.0 beta your Baseband will be at 05.13 and you may not be able to unlock to use until the next release of ultrasn0w and blacksn0w.
  • Redsn0w 0.9.5 uses the same pwnage2 DFU-mode exploit that the Dev-Team has been using since the 2.x days.
  • The current Beta of Redsn0w 0.9.5 is not for normal users so if you are not a developer stay away
