Redsn0w 0.9.5 beta 4 is out now to jailbreak iPhone OS 4.0 beta 4 firmware. The iPhone Dev-Team has released redsn0w 0.9.5b4 to jailbreak iPhone OS 4.0 so that the developers of jailbreak apps can fix the issues with their apps and get them ready before the availability of iPhone OS 4.0. So, Redsn0w 0.9.5b4 is meant for developers only NOT for end users.
Please note that Redsn0w 0.9.5 beta 4 is a Jailbreak tool NOT an unlock. iPhone OS 4.0 beta 4 contains a Baseband update which is not unlockable ATM.
This is a beta release of redsn0w targeted at developers of jailbroken apps. It uses the same pwnage2 DFU-mode exploit that we’ve been using since the 2.x days. Nothing new is revealed to Apple, and it’s not applicable to the iPad. Don’t go near it if you use yellowsn0w, ultrasn0w, or blacksn0w.
Because it’s meant for JB app developers, this beta redsn0w does not perform hactivation. You’ll need a properly-registered developer UDID with Apple to get past the activation screen. For similar reasons, there is no Windows version of this beta redsn0w (since apps are developed on MacOSX). Please don’t pirate Apple software.
YOU SHOULD STAY CLEAR OF THIS BETA SOFTWARE IF YOU RELY ON A CARRIER UNLOCK. That’s because the beta redsn0w works only if your device has already been upgraded to the stock 4.0beta1/beta4 IPSW from Apple, which contains a baseband update. If you installed that IPSW, you’ve already lost the carrier unlock until the next planned release of ultrasn0w and blacksn0w.
Redsn0w 0.9.5b4 Supports:
- iPhone 3G only (for now)
- Mac OSX only (for now)
- the 4.0beta1/beta4 FW only (for now)
