No Limera1n or GreenPois0n icon on iPhone/iPod/iPad's SpringBoard after Jailbreak? You're just doing it wrong.

For those who didn't know, SpringBoard is the home screen of the iOS, the screen where all of your apps are located. I won't tell very much about Limera1n or GreenPois0n, they are just jailbreaking applications (Limera1n works on Windows and Mac, while GreenPois0n has a version for Linux also). Basically, they are quite the same thing (they're using the same exploit), and they work with any iDevice running 4.0, 4.0.2 or 4.2 firmware.

They are both very easy to use, you just have to download, run, and click "Make it ra1n!", and you'll be told how to put your device in DFU mode in order to start jailbreaking your device. A problem experienced by some of the people who tried jailbreaking their iDevices was that there was no Limera1n/GreenPois0n icon on the SpringBoard after jailbreaking (even though the applications said that jailbreaking succeeded).

The idea is that iTunes (it doesn't matter what version it is, it just needs to recognize your device) must be kept running while jailbreaking. Don't ask me why, I also had that problem, and when I left iTunes running while I used Limera1n, my jailbreak succeeded (when you see that drop rain on your iDevice, it means that jailbreaking succeeded). Probably, there's something in iTunes which allows the device to receive data while in DFU mode.

Who would have thought that there's such an easy fix for this problem?

Limera1n/Greenpois0n and iPad on 3.2.2? Better...not.

If you've got an iPad and you want jailbreak on it, my recommendation is to avoid the update to 3.2.2 (if you haven't done it already). My iPad was bricked today by a an app (it was stuck at boot logo), and I decided that because there was no way of recovering the data I had on it, the best option was to update it to the latest firmware, 3.2.2. But it turned out that it was a bad idea....

Everything went fine, iTunes 10 successfully updated it to 3.2.2, but the problems started when I tried to jailbreak it. Even though it seemed that the jailbreak succeeded, I couldn't find on the home screen the icon/shortcut/logo/app/whatever of the jailbreak tool I tried. I tried both limera1n and greenpois0n, on three different computers. One was running Windows XP, one was on Windows 7, and the other was on Mac OS X. However, on none of the them I got the icon of the jailbreak solution I tried. So, I couldn't get Cydia, so the jailbreak was completely useless.

I really don't know where's the problem, some people reported that both solutions worked fine from the first try on their 3.2.2 iPad, others reported that they tried of few times and than they succeeded, and others reported that they got in the same situation as me. I think that I tried about 25 times to jailbreak that iPad. I really got tired of these iDevices. Unjailbroken, the iPad it is just a bigger iPod, even a much cheaper Android-powered device being able to do much more that an iPad can. But if you jailbreak it (it's legal in case you didn't know, read more here), you'll get a big headache with all the bugs and problems jailbreaking brings.

I ended up by restoring the iPad to 3.2.1 (I had SHSH on file for 3.2.1, so it was quite simple), and I did the jailbreak using jailbreakme.com. If you're still on 3.2.1 (or 3.2) and you want jailbreak, make sure you do it before updating the iPad to 3.2.2, because at that time you can save your iPad's SHSH blobs without any problem.Having SHSH saved on 3.2.1/3.2 (or even on 3.2.2 if you get there with a jailbroken iPad) means that you can anytime downgrade/restore to the version you have that SHSH saved.

Use them on your own responsibility:

Jailbreak by greenpois0n (Windows, Mac OS X, Linux): http://www.greenpois0n.com/

Limera1n is available, jailbreaks iOS 4.0-4.1.

Limera1n has been released yesterday evening, and after geohot got angry and pulled the download link (I don't know exactly why), it seems that Limera1n is now available for download again on the official website. This new jailbreak tool promises to jailbreak almost any device running iOS 4.0 or 4.1.

The supported products are iPhone 3Gs/4, iPad, and iPod Touch 3G/4G. For the unmentioned products: iPod Touch 2G support is coming soon, while for the iPhone 3G you must use redsn0w. For the moment, limera1n is available only for Windows, the compatibility for Mac is coming soon.

Theoretically, limera1n does hacktivate your device (allowing you to use it with any carrier), but many people reported problems after hacktivating their iPhones with limera1n, so I don't recommend you doing this yet (limera1n is currently in beta 4).

Hope I don't have to tell you that you're using it on your own responsibility, it is an unstable release so don't expect from it to be bug-free. You might have to restore your device or you may even get a bricked one as a result of using limera1n!
