Limitations: Careful, New iPhone Users

After reading: Setting Up the Untethered Jailbreak with Geohot's Blackra1n, I was positive that I'd be able to jailbreak my iphone and update to the latest iOS without a computer.

The instructions were clear and the details comprehensive. Not to mention, I had the guts to be one of the first to try this untethered hack!

I was stopped dead in my tracks, however, when I hit the 3G sign and Cydia struggled to install.

Over the next 30 minutes, I became increasingly frustrated as I continued to try to create the required environment for the untethered jailbreak. To make matters worse, when I followed Geohot's advice to update iTunes, my iphone was rendered useless and I couldn't even boot it up to update the software manually. (I was definitely not the first.)

As a newbie iphone user, I was too impatient to deliberate and used the 3G sign to bypass the need to connect with a computer before doing the jailbreak. Like an idiot, I had manually updated my iTunes (version 7.3), which froze my iphone and made my computer unable to recognize it.

Untethered Jailbreaking: How to Jailbreak Without a Computer in the Real World

If you are jailbreaking your iPhone with the intent of using it longer than a day, year, or beyond then you will need to jailbreak untethered. Untethered jailbreaking means that you don't reboot your phone after jailbreaking and it keeps the jailbreak.

Nowadays, there are a few untethered jailbreak methods. The easiest of these is Redsn0w. For those that don't know, Redsn0w is a jailbreaking program that works best when run on Windows computers. However, there is currently a way to use Redsn0w on a Mac.

Why is this so important?

Imagine you have a job where every 30 days, your phone will erase all its data and return to its factory settings. During this time, your iPhone will not be able to use any apps that haven't been approved by your company. This is what happens when you do a tethered jailbreak using a program called Absinthe.

If your iPhone sees an unauthorized app on it, it will erase everything it can to make sure that it can't be used. This is desirable for companies that do not want their employees to install unauthorized apps in general. This is why Absinthe will only allow you to jailbreak a tethered jailbreak.
