Ven1 vid1 ja1lbreak1: Hands on with blackra1n
When it came time recently to jailbreak an iPod touch, I decided to take a look at George Hotz's BlackRa1n tethered solution. Unlike the Pwnage approach that creates a custom ipsw (iPhone software) bundle that you install via iTunes, the tethered approach communicates directly with your iPod or iPhone via the USB connector cable you use for normal syncing. That makes the tethered solution a very fast and easy-to-use approach, especially for units shipped with the 3.1.2 software installed.
Download the BlackRa1n tool for both Windows and Mac from the GeoHot site. Complete instructions are available at his Weblog. If you own more than one iPhone unit, make sure you unplug all but one from the system before you start the jailbreak. Launch BlackRa1n and click the "make it ra1n" button. Then be patient and wait as the software does its job, including replacing your recovery logo (normally a picture of the iTunes logo and the connector cable) with a vanity image of the software's author.
Be aware that the blackra1n jailbreak may present issues during reboot, forcing you into recovery mode and requiring BlackRa1n to launch properly. Hotz writes, "If your ipt2/3GS/ipt3 is rebooting into recovery after running blackra1n, this isn't a bug. It's a feature. You need to run blackra1n every time to boot it. This 'feature', called tethered jailbreak, is enabled by upgrades Apple made to the bootrom and the fact ipt3 uses nand flash." I did not experience this behavior on my iPod touch 2nd generation unit. It reboots without problem, and, no, it had not been jailbroken before.
Once the jailbreak has finished and your iPhone has rebooted, you can run the on-device version of the BlackRa1n software to install Cydia, the Rock store, and (for iPhones) the sn0w unlock that allows phones to be used with other carriers.
I found the whole process extremely easy to perform and would recommend it to anyone who had difficulties using Pwnage. The trade off, of course, is an easier install versus possible long-term reboot issues. It seems that my touch ducked the bullet on that one but that's only one experience among many.
Although BlackRa1n is free software, the author asks for donations to support this effort, so he can continue providing tools in the future. A donate link appears on his home page.

I couldn't wait to jailbreak my first gen iPhone and once accomplished, I loved all the amazing extra capabilities (pre app store), themes, video recording, games, etc. I never went full bore and unlocked it to be free from ATT since there was nowhere to go in my case. Then came the iphone 3g with the app store and I realized the only thing I was getting from jailbreaking was themes (why we still can't legitimately do this is silly), and I was putting up with a lot of instability for those icons, so I quit messing with the roll your own stuff and went back to the sanctioned OS. Now I have a 3GS and have no desire to jailbreak. I've probably spent $20-30 on more apps than I have time to play with, and some I depend on daily. I would NEVER knock the JB community, without those great hackers early on, we may not have gotten the app store and other capabilities as soon as we did. I believe they really lit a fire under apple's a**. Keep pushing guys, cheers!

Simply a matter of hitting Restore in iTunes and resetting to factory settings?
So now TUAW is advocating hacking and piracy? Nice.

I prefer this method to pwnage, it's easier, faster, and doesn't require a full install. I've experienced none of the problems mentioned in the article (or on the comments) and the rock app surprised me, it's much better than cydia!! Cydia has ignored the app portion of it's store, i find it almost unusable waiting for it to refresh ever couple minutes!
great review!
I have it on the 3GS (new as of two weeks ago) and I have the reboot issue. Every time it starts up from being completely shut down, whether by a crash or me manually turning it off, it goes into DFU mode and I need to use Blackra1n to fix it. I turn it off very rarely and it has only crashed 2 times (I assume from one of my jailbreak apps), but it is still annoying. Fortunately I take my laptop almost everywhere with me so it's not the end of the world if it happens.
I find myself using less and less jailbreak apps, but I still find SBSettings, Backgrounder, and Kirikae too essential to pass up on. I constantly have to adjust my brightness and turn on/off my bluetooth, and to have to go into multiple pages of the Settings app is too disruptive, especially while I am driving. SBSettings solves that problem. Furthermore, certain apps that require a lengthy loading/downloading time (RSS apps, for instance) are great to start up, put in the background, and return to once they're ready for viewing. So the tethered bootup, for me, is annoying but absolutely worth it.
I used it for my touch. It works great and I have had no issues with it. The only problem is that you can never really turn the touch off completely or let the battery drain. A tether is required to get it back to running properly. No big deal for me. Maybe for others. But I have had no issues with it.
Another point worth noting. I gave up Cydia and use Rock now. And IMHO, Rock is TONS better.
Just my $.02
My understanding (and experience when I tried it on my iPhone 3GS) was that you only need to use the blackra1n app to reboot your phone if the battery drains out completely. The normal hold sleep button, slide to power off, hold sleep button again to boot up worked just without being tethered.

December 07 2009 at 11:35 AM Report abuse Permalink rate up rate down ReplyThis was the main reason I decided to jailbreak my device, and it lead to my baseband crashing at least once a day, usually when I wanted to make a call. Reverted the hack, and the problem went away. YMMV.

program came out November 3rd, here:

I even used an already unlocked 3G, which I then upgraded to the new
evil baseband, to demonstrate that this would work. It went off without a hitch.
I've used Marks site above (hackthatphone.com) as an instruction manual before nearly every update and it has made the unlock process so much easier. The jailbreak tools from the iPhone Dev team are great but having a solid walk through from hackthatphone is super helpful.
No affiliation with the site, I just want to highlight
how useful I've found it to be.
After I used blackra1n to jailbreak, my iPhone would occasionally not pick up any wifi signals at all. I believe I'm not the only one, but by no means do I speak for everyone who jailbroke using blackra1n. After I got bored of restting network settings every other day, I decided a fresh install was much better.
December 07 2009 at 11:20 AM Report abuse Permalink rate up rate down ReplyThere is fix for that. I have used blackra1n on my iPhone 3GS with baseband 05.11.07 and everything works perfectly. It is also the easiest and fastest jailbreak around. My iPhone also reboots without the need to use blackra1n again...
