The iPhone Dev-Team has released a beta of RedSn0w 0.9 which performs jailbreaking, unlocking, and customizing for the latest iPhone firmware.

Customizations include boot logos, recovery logos, and “verbose” boot.

The 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

When it's out of beta, it will support the iPod touch 3G, PPC OSX, and Linux.

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.

How is it different from blackra1n?
- It uses our 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 that exploit will be fixed in Apple's next FW release.
- It offers custom logos and verbose boot
- It installs Cydia without needing a separate download
- It's not as fast :) (but redsn0w handles more variations :))

If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC”, you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. That means you need to connect your device to a computer to complete the boot after a reset. Also, these devices cannot have custom logos.

We will be posting detailed tutorials on how to use RedSn0w 0.9 as soon as the beta is finalized. Please stay tuned for more information.

Hello, I have an iPhone 3GS (3.1.2), model # start with 'MB'. The phone was JailBroken & unlocked with BlackRa1n, but the phone lock down every time it turn off. So I was wondering if I JB n unlock it with Redsn0w 0.9 Beta, is that gonna help? Thax in advance!!

John - January 22, 2010 at 1:15pm

no, it's still tethered for iPhone 3GS with new bootrom a.k.a. no it's not fixed!

FranK JR jr - January 21, 2010 at 8:39pm

This is just not working for me. it just stays on a black blank screen and never shows the pictures or anything. hopefully theres a fix soon

Jay - January 21, 2010 at 3:44pm

Well this is almost pointless.... Someone should tell the Dev Team about Apples iPhone 4.0 coming NEXT WED! A little late on this one guys. I also suggest BlackRa1n!

fenrry - January 21, 2010 at 3:52pm

Is not pointless, ur rt about the new OS if they really do release such thing but on the mean time is a good start.

Edgar - January 21, 2010 at 4:38pm

Not a 100% confimed that they'll announce it next week. On top of THAT, if they DO, they probably won't release it next week either.

battery lifeeeee - January 21, 2010 at 3:03pm

do u think if we jailbreak using redsnow your battery life will improve? blackrain is a battery killer. but theres no other choice right now?? any suggestions on getting batt life? im using a 3gs 32gb purchased 1 month ago. jailbroken with blk rain --wifi always offfff :)

Steve Anderson - January 21, 2010 at 3:29pm

blackrain doesnt kill battery once yr phone is jailbroke you delete black rain its iphone batterys are crap anyway try a original iphone with no jailbreak battery life is the same as a jailbroke phone

Luis Felipe - January 21, 2010 at 8:49pm

heyyy!!!! wi-fi it´s always off on mine too!!!! sometimes I try rebooting with blackra1n and can get wi-fi working well... but now... it´s off and I can´t get it back on... do you know the reason why or at least a forum to go and check for answers.... thz!!!!!

Luis Felipe - January 21, 2010 at 9:06pm

how do I delete blackra1n....???? and... is this gonna affect my iphone performance....??

chriskat - January 22, 2010 at 5:37am

hi, just open the blackra1n app on your springboard and is a button to uninstall blackra1n, you will only be uninstalling the app not the unlock, the jailbreak or cydia/rock

cristian - January 22, 2010 at 10:03am

You are right. I installed blackra1n two days ago and I noticed the same thing. It drains the battery very quick. Is there any fix to this?

Dan - January 22, 2010 at 11:01am

blackra1n does NOT kill the battery. I've been jailbroken with blackra1n for a few months now and can easily go two days with a few calls and data usage. I leave all the radios on all the time. I'm guessing that you installed a bunch of crap from cydia/rock and something there is causing your battery drain. blackra1n by itself does nothing that I can see to kill battery.

chriskat - January 22, 2010 at 11:41am

i have had blackra1n installed from day one one both the 3G and the 3Gs and it is not the battery killer, it probably is something else you have installed, also the 3Gs is not the best for battery life. i usually get about two days with normal use which seems to be the norm.

Luis Felipe - January 22, 2010 at 3:19pm

how about the wi - fi thing...?? thanks for all your answers...

Dan - January 22, 2010 at 3:43pm

The only wi-fi issue I've had also occurs when not jailbroken. At work we use Cisco access points serving up multiple SSIDs. The only SSID the iPhone can connect to reliably is the SSID that is in the clear and is broadcast. The hidden SSID with WAP will not connect reliably (connects then disconnects, repeat). The other issue I have...again, both vanilla and jailbroken is with the VPN client. It connects, but only for a few minutes and then disconnects. I think the iPhone software still has plenty of bugs....especially when you get to things that the average user might not come accross (multipl SSID APs and VPN).

chriskat - January 22, 2010 at 6:34pm

have you tried a complete restore and re-jailbreak, i had a few issues with battery life and wifi when i upgraded to the 3Gs so what i did was (make sure to back up your iphone with itunes before doing anything) just restore your phone with itunes but set it up as a new phone NOT from a previous back up (you can sync all your contacts afterwards) when the phone is now stock apple firmware you can see if you still have the problem then jailbreak and unlock, if that doesnt work you can allways restore the phone again and set it up from your initial back up. it may not work but it might be worth trying

Jaidev - January 21, 2010 at 2:31pm

What is meant be "late model iphone." My one was purchased in September and is tetherbroken with blackra1n. Is this supported for my iphone 3gs?

DuB - January 21, 2010 at 2:54pm

Yes yours is supported but you will still have a tethered jailbreak. But if you are jailbroken on 3.1.2 with blackrain there really is no point to re jailbreak. Unless you have a need for verbose boot.

MegaTZ - January 22, 2010 at 8:38am

Does this actually unlock? It didn't say so, and ultrasnow still doesnt work with 5.11 bootrom. the JB went perfectly.
