RedSn0w 0.9 Beta for Mac and Windows is Released by iPhone Dev-Team

redsn0w-399x294

The iPhone Dev-Team is back, this time with the first beta of RedSn0w 0.9 for Mac and Windows. Version 0.9 will allow for jailbreaking, unlocking, and customizing of the iPhone OS 3.0/3.1.2 software. It is important to note that this beta supports every iPhone and iPod touch with the exception of the iPod touch G3. (That will be supported after the beta period is over.)

For quite some time now blackra1n has been the most-used tool to get your jailbreak on but the way this new version of redsn0w works, could that change? You see this software uses the original Pwnage bootrom exploit from iPhone 2G, iPhone 3G, and iPod 1G. What this means is the only way for Apple to combat it is via a hardware change. However, for the iPhone 3GS and iPod 2G running 3.1.2, things are a little different as they still use the USB exploit that is said to be going away with the iPhone 4.0.

Due to some last minute forum software changes, the Dev Team

If you'd like to check it out for yourself, the Mac version can be downloaded here while you can grab the Windows version here.

I've avoided blackra1n because of the tethered jailbreak issue with my 3GS on 3.1.2. Is this a tethered jailbreak, too?

Cant wait till they release the official redsn0w :)
I don't like having a tethered iPod :P

If you have a newer 3GS with the new bootrom, this will /still/ be a tethered solution. Get used to it. No one's found a hole in the new bootrom yet. And if Apple has been very good at it's job, it won't happen anytime soon. The good news for those reselling older iPhone versions is that this kind of BS will enhance their value! :D

What its exactly tethered jailbreak? I have blackrain and i can download music and turn off the phone without damage

@Dan- you're not getting it. A tethered jailbreak requires you to rejailbreak (while connected to your computer) anytime you reboot your iPhone. If your battery runs out and you don't have access to your computer, you're screwed. This has nothing to do with tethering to make your iPhone a "modem".

Gotcha,
im assuming you have the new bootrom ? cause i have no such issue w/ mine on blackrain w/ 3.1.2

? My 3gs is only a couple months old and by your definition Im not teathered. My jailbreak is fine when I restart the phone or run out of battery. I
how recent is this bootrom change?

Well I got my iphone back in September and I have no issues. I believe it was in oct/nov when the change happened.

@Bill Tarolli: I have an iPhone 3Gs, and upgraded via iTunes to the latest firmware then used blackra1n. I've since rebooted my phone SEVERAL times and my jailbreak persists.

@Christopher Cox...you're not paying attention. It's not just the firmware, it's in the BootROM, and it's only on iPhones that have came out in the past couple of months.

I'm surprised GeoHot didn't disable jailbreaking for the 3GS with the new bootrom. It is a huge safety liability and he opens himself up to lawsuits. Imagine if somebody tried to make an 911 emergency call and the phone wouldn't work because of this.
Also, think about the guy in the Haiti earthquake. I'm sure he wasn't keeping his iPhone on the whole time, or the battery would be dead within a day.
Anyway, there's no way I would jailbreak if I had to tether each time...

Tethered is the reason I stopped jailbreaking my iPhone . Twice when I was on the road I had the springboard crash on me and restarting the phone made it unusable unless I had a computer handy ( which I didn't )

I used PwnageTool to JB my 3G on 3.1.2 when it came out a few months ago. I didn't think I would ever need to unlock, but now I do.
Can I use redsnow to unlock? Or do I need to restore and re-jailbreak with redsnow to use redsnow to unlock?

what is meant by this statement?
"However, for the iPhone 3GS and iPod 2G running 3.1.2, things are a little different as they still use the USB exploit that is said to be going away with the iPhone 4.0"
does it mean with iphone 4.0, tethered JB'ing won't be an issue? or does it mean, JB'ing will be next to impossible by current means?

Im glad I bought a older 3gs off craigslist.... It would suck to have to do a teathered jailbreak... Thats horrible lol!! I would explain to you guys but I cant find the thread.. Your phone will have the new bootrom if the serial number is over 49 or something I forget.

It means the way blackra1n exploits the iPhone to jailbreak it possiably won't work anymore. Hence the reason for redsn0w using the bootrom exploit.

Ok sorry this is how u find out if you have the new bootrom...
The serial number is one way to check; if the 3rd, 4th, and 5th digits of the number are 940 or higher it more than likely has the new bootrom. If it is 939 or less you should have the old bootrom; there may be some iPhones that don't fit into that criteria so here is how to check the bootrom and know for sure what you have (no jailbreak is required):
I think this jailbreak is still teathered...

Isn't there a known untethered exploit for the 3gS and 3rd gen ipt? Supposedly they are saving it for 4.0 or the next device. Also, a semi-tethered break is coming out for the time being? ie; ability to boot device without jailbroken apps untethered.

Tethered jailbreak doesn't cause me any problems. Only ever needed to do it once at the start. What is the big deal? Am I missing some major problem that is currently un-apparent to me?

I have a newer 3Gs with the new bootroom that's currently jailbroken with blackra1n, tethered. Will this redsn0w allow me to have an UNtethered jailbreak ????

It's great how you can change your boot logo then keep your old jailbreak. And you can keep on doin it!

I have my 3GS tethered jailbroken and it does not bug me one bit. I've had occassions where it died but my computer was nearby. As long as my device is able to be jailbroken, tethered means nothing to me.

Jus tried the beta3 on my 3gs running 312 with 943 bootrom. Was cracked/unlocked with blackra1n but this one ran fine. I'm not sure what its done but seems to be working fine even after a reboot.
I'm hoping its protected me for 4.0.

"You cannot open the application "redsn0w.app" because it is not supported on this architecture"
WTF? Can't run on Tiger?

“You cannot open the application “redsn0w.app” because it is not supported on this architecture”
WTF? Can't Run on mac os x 10.5.8

nick or jmm had any joy this "not supported on this architecture warning? iv got the same problem on my mac 10.5.8 i tried an older mac (the old mans) on 10.4.11 with an older redsn0w tool and i got the same problem then always so i guessiv always had this problem with redsn0w tools

I have figured out a way to fix the error "not supported by architecture". Just update to a newer version of osx... Even though this is virtually impossible for me as i am on a PPC. :-(

okay... i might just be an idiot, but i downloaded the newest version of redsn0w but i can't open it... i guess i'm downloading it wrong... any advice?

Hey. So i download Redsn0w on my Mac book but it just comes downloads it as a ZIP file. Is this what it is suppose to be? And if so what app can i download to run it. Nothing seems to work?

You have to be careful, it's a bit tricky. The download appear in the top page is for the zip utility. You can find the RedSnow link on the bottom of the page.

hye admin..i just wanna ask u something/just need your opinion on something:
1. can i jail breaking my macbook pro OSX 10.7.3 (lion osx) by using cydia same as iphone4?
if its possible, can u show us how to do and how its work?
