As of now, the iPhone Dev Team’s redsn0w 0.9.5 jailbreak tool can effectively hack a device running the iPhone OS 4.0 beta from Apple. The jailbreak only supports iPhone 3G, and doesn’t preserve / provide carrier unlocks. According to the code-savvy people behind redsn0w, this hack is only for developer types.
“This is a beta release of redsn0w targeted at developers of jailbroken apps,” the latest update over at iphwn.org reads. “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,” it warns.
“Please not[e] that this beta is not meant for the average end-user,” another warning goes. “There are many things ‘broken’ with jailbroken apps in the 4.0beta1 environment right now (that's the real reason we showed ‘Veency’ in the 4.0 jailbreak demo video last week, instead of say MobileTerminal.app, which is broken!). This beta redsn0w allows the developers behind those jailbroken apps (like MobileTerminal.app!) to fix their software before the general public gets iphoneOS 4.0,” the team explains.
redsn0w too is in beta, the post reveals, and it does not perform hactivation. The team stresses that, even if you have an iPhone 4.0 beta IPSW lying around, you’ll still need to activate it first, in order to use the jailbreak. Also, it notes, there is no Windows version of this beta redsn0w. The team then writes with capital letter that users who rely on a carrier unlock should stay clear of this beta software. “If you installed that IPSW, you've already lost the carrier unlock until the next planned release of ultrasn0w and blacksn0w,” the team informs.
