After a long time devteam came out with their new version of redsn0w which supports
- All current iPhones & iPod touch models except the iTouch 3G
- Windows OS and Mac OSX (x86, Intel) based computers
- iPhone OS / iOS firmware 3.0 and 3.1.2
Currently it is in beta and once when it’s out of beta, it will support the iPod touch 3G, PPC OSX, and Linux.
If you need a carrier unlock, redsn0w will handle iPhone 2G by itself by installing our BootNeuter utility, Earlier we were doing this manually.
For the 3G and 3GS, use Cydia after you’re jailbroken, install ultrasn0w (baseband 04.26, preferred) or blacksn0w if your baseband is 05.11.
It differs from blackra1n because:
- It uses the original Pwnage bootrom exploit for iPhone 2G, iPhone 3G, and iPod 1G. (Because it’s a bootrom exploit, it can’t be fixed by Apple without a new hardware release.) Note that redsn0w 0.9 does use the USB exploit for iPhone 3GS and iPod 2G running 3.1.2, but expect the exploit to be fixed in Apple’s next FW release.
- Redsn0w offers custom logos & verbose boot
- Cydia is downloaded automatically without any more effort
- It’s not as fast 🙂 (but redsn0w handles more variations 🙂
If anyone has a late-model iPhone 3GS, or an iPod touch 2nd generation whose serial number begins with “MC”, they can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting.
redsn0w will ask you whether or not you fit in this category when used with the iPhone 3GS or iPod touch 2G. If you have a late-model device and don’t give redsn0w the correct answer, you will likely need to do a system restore to recover from the mistake.
To do a tethered boot after your late-model device resets for some reason, either run redsn0w again and select “Just boot tethered right now”, or run blackra1n.
If you’re already jailbroken (by whatever means), redsn0w can still be used to change your boot logos, revert to the stock logos, or switch verbose booting on and off. By selecting “Already Pwned” you can bypass the steps normally needed to enter the jailbroken state.
You should see a picture of a drive (“Downloading Jailbreak Data”) within 30 seconds of launching the jailbreak (after you’ve made your custom selections). It should then reboot, and you should see a running pwnapple while the process is underway. It should finish within a minute or two after that and will reboot on its own.
