iPhone 4.1 Jailbreak
The reason for doing an iPhone 4.1 jailbreak remains to be the same as what you would have for the previous versions of the iOS. Do an iPhone 4 jailbreak and you get to enjoy immense freedom that would let you use applications rejected from the Apple App Store and do system customizations. Without an iPhone 4.1 jailbreak, you can’t do these things, leaving you stuck with applications and settings assigned by Apple. This isn’t to say that applications from the App Store suck, because they don’t. In fact, there’s practically an application for you to take advantage of for virtually any need you might have. It just so happens that some of the applications you get access to when you unlock iPhone 4 are far better than their Apple-approved counterparts. But while your reasons will be the same, an iPhone 4.1 jailbreak is different from the 4.0 version.
Before doing an iPhone 4.1 jailbreak
Keep in mind that doing an iPhone 4.1 jailbreak has its risks. Yes, it is fairly simple to do but it is not without its risks. What kinds of risks are you looking at? The worst that can happen to you is that you end up with a brick for a phone. The least is that nothing will happen, and it will seem that you just wasted precious minutes of your life. Whatever happens after an iPhone 4.1 jailbreak, please remember that this voids your Apple warranty.
Doing a jailbreak iPhone 4.1
The iPhone 4.0 jailbreak had you using the JailbreakMe hack. With an iPhone 4.1 jailbreak, you’ll be using Limera1n. The Limera1n will require a download and the use of a PC, while the JailbreakMe hack was a simple matter of loading a site in your iPhone. To get started with the Limera1n iPhone 4.1 jailbreak hack, you have to hook up your iPhone to iTunes and do a full backup. Once iTunes is done backing up your iPhone, run the executable for Limera1n, and click on “make it ra1n”. When it says so, hold down the power and home buttons. Do this for a few seconds and wait until it prompts “release power button”. Release the power button but make sure you keep holding the home button down. When you see a “in DFU modewait” message, you can release the home button. A “Done” message should pop up in under a minute, and your iPhone will shut down by itself. And you’re done! Just turn it back on by holding the power button down.
