The iPhone Dev team is back and has just released Redsn0w 0.9 Beta n alternative for blackra1n. If you have performed jailbreaking on iPhone on iPhone OS 3.0, you probably know what redsn0w is. At that time, it is a very popular jailbreak and unlock tool that supports both Windows and Mac platform.


The previous version of redsn0w supports iPhone OS version up to 3.0. Now, redsn0w 0.9 beta supports:

- All iPhones and iPod touches except the iPod touch 3G
- Windows and Mac OSX (x86)
- Apple firmware 3.0 and 3.1.2

According to iPhone Dev team, redsn0w will also support iPod touch 3G, PPC OSX, and Linux when it’s out of beta.

As of now, blackra1n is the easiest and fastest jailbreak tool for handling iPhone jailbreaking. Redsn0w, however, offers additional customizations that allows you to alter the boot logo and recovery logo, as well as, switch to verbose boot. While blackra1n breaks jailbreaking, unlocking and installation of cydia into different processes, redsn0w combines all these steps together. Say, you selects jailbreak, unlock and “install cydia” options together. Once the whole jailbreaking process completes, the iPhone will be unlocked and installed with cydia automatically.

For those using the latest model of iPhone 3GS or iPod touch 2G with serial number begins with “MC”, you can still jailbreak it using redsn0w but only tethered jailbreak is available. That mean, every time after reset, you need to connect your iPhone back to computer to complete the reboot.

How is it different from PwnageTool?

Redsn0w doesn’t require a system restore like PwnageTool does (it doesn’t even use iTunes at all). On the other hand, PwnageTool can prevent your baseband from being upgraded when you upgrade your firmware, preserving your unlock. (redsn0w doesn’t touch your baseband but it doesn’t help preserve it during an upgrade either). redsn0w works by modifying your current filesystem, so your existing baseband, data and applications should remain intact.
