What is Jailbreaking?

What is Jailbreaking?

The process of jailbreaking takes advantage of exploits, or imperfections, in either the software or the hardware of an iPhone, iPod touch, iPad, or Apple TV. By doing this you can remove the limitations implemented by Apple and so you can then install third-party apps, tweaks or modifications, and even themes to change the appearance of your device; all of which are not available in Apple’s App Store.

Apple applies numerous safegaurds to iOS which prevents users from installing and running software which has not been approved by them. They do this to protect the devices and users from threats like bugs, crashes, and even viruses so this method can be extremely beneficial to the run of the mill user, making iOS and easy to use and more importantly, stable operating system. While this may be good for most people, many prefer to extend the potential of their devices and make them stand out from the crowd and these two reasons are why I’ve jailbroken every single mobile Apple device that I’ve owned.

Is Jailbreaking Legal?

Many people muddy up the answer to this question and don’t provide a straightforward answer. To put it simply, in the United States, under the Digital Millennium Copyright Act, jailbreaking iOS devices is legal as it is in every other country with the exception of Canada. In Canada, the Copyright Act was amended in 2012 prohibiting tampering with digital locks. This is exactly what jailbreaking does and so it is illegal in Canada, however, there’s really no way for the government to  find out if you do it so you might as well take the leap and just do it. Now while it is legal pretty much everywhere, you will void your warranty with Apple so if you take your jailbroken device into an Apple store for help they’ll void your warranty. But what you can do is simply restore it iTunes and if you still have the problem you can take in to Apple and there’s no way they’ll ever know if you jailbroke your device.

How do you Jailbreak?

For the most part, jailbreaking tools are just programs that you can download for your Mac or PC. Normally they have you go through a few steps like holding down a few buttons on your device and they’ll do the rest. Other times programs will create custom IPSW files, or iPhone SoftWare, and will then require the user to restore to that custom file (which has the jailbreak bundled with it) using iTunes. But sometimes there are methods that just use Mobile Safari. So you open up Safari on your device, go to a specific website, tap a link, and it’s done. But, different methods are needed for different exploits and so some jailbreaks may be extremely easy while others may require your computer and a few minutes of your time.

Who Develops Jailbreaks?

So far jailbreaks have either been developed and released by independent developers like GeoHot and Comex, or by teams of developers and security experts like the iPhone Dev Team, Chronic Dev Team, and evad3rs.

Basically, the way jailbreaks are put together is that developers look for exploits, or holes, in the software or hardware of a device. Sometimes it could only take one exploit and sometimes it can take as many as twenty for a single jailbreak, but once they’re found it gives the developers a chance a to insert their own code into the device in order to bypass Apple’s limitations. These guys do this in their free time, which can often take months from the time Apple releases a new version of iOS or a new device, and these jailbreaks have always been completely free to download and use.

Cydia

Every jailbreak process installs another “app store” of sorts called Cydia. Originally, when jailbreaking first started, we had another app called Installer but since iOS 2 Cydia has been the big player. Like the App Store it lets you search for tweaks and themes and modifications and then install them. The difference of course is that Cydia only runs on jailbroken devices and the software that it provides you with has not been approved by Apple.

Cydia uses repos, or repositories, which host all of these tweaks, themes, and other software. They basically act as channels, allowing you to download and access the customizations. And, just like the App Store, while many packages are free there are some which cost money.

How do Jailbreaks Work?

Jailbreaks provide users with root access to iOS, allowing non-Apple approved software to be installed. This is done by exploiting flaws in the device’s software or hardware.

There are two levels of jailbreaks: tethered and untethered. A tethered jailbreak requires the device to be connected to a computer and then re-exploited with jailbreak software each time it boots in order to remain in a jailbroken state; otherwise, the device will boot as if it is not jailbroken and none of the tweaks, modifications, themes, or jailbreak apps will work. With an untethered jailbreak a user can properly reboot their device without being connected to a computer while retaining the jailbreak.

The most important concept to understand about jailbreaking is that a jailbreak does not exist for every version of iOS nor for every iOS device. For the most part there will be one major untethered jailbreak released per year with each new major update to iOS like iOS 6 or iOS 7. Apple will then release smaller updates which will fix bugs and patch the exploits which were necessary for the jailbreak. Often times the developers will release updated jailbreaks so that anyone who updates or purchases a device with the new version of iOS can jailbreak their device. But, just as often, they don’t release an updated jailbreak in hopes of preserving the exploits that they’ve found for future major jailbreaks.

2011-2013 Mustang V6 Roush Exhaust Sound Clips & Review

The Roush axle-back exhaust system for the 3.7L 2011 Mustang V6 is in a class of it’s own. They’re some of the most affordable mufflers and add some of the most noticable differences than many other after-market axle-back exhausts. It’s agressive exhaust note makes the V6 Mustang sound what is was born to be, a true American muscle car.

The exhaust note dampened a bit after about 100 miles but it was so insignificant only the driver will notice. At idle it completely transforms the sound to that of a V8; nice and deep, loud, and bassy as well as below 2000 rpm. When the revs climb above 3000 rpm the Roushs absolutely scream and become a bit raspy while keeping a bit of a low tone in the background and then slightly deepen again around 6000 rpm. They’re quiet while coasting so one would without a doubt want to coast by any cops.

There is a significant amount of drone but definitely not the worst in the after-market exhaust market. The drone is obviously the worst at 2000 rpm and is managable around 1700 rpm. Overall it’s not really a big problem to hold a conversation with a passenger or while listening to the radio.

The mufflers and tips look great on the Stang. The large 4″ polished tips outshine the cheap stock tips on so many levels and the smaller mufflers (“cans”) are almost unoticable making for a much cleaner look. The entire look of the back end is improved because of these mufflers (or any other similar looking mufflers for that matter). Installation shouldn’t be too hard, it’s essentially loossening the stock mufflers and removing them from the hanging rubber brackets and then doing the reverse with the Roush axle-backs. However, if you can’t find a way to lift the car off the ground (or at least the rear wheels) you’ll have to take it into a shop to have them installed which can typically cost up to $100.

A major thing to note: the noise level (while obviously loud throughout the spectrum) is determined by how hard the throttle is punched. The harder the throttle goes down the louder (and higher pitched) the exhaust is. Overall these Roush axle-back exhausts are much, much louder than stock and it isn’t difficult to see why so many people end up returning them or reselling them because they think they are too loud and obnoxious. Lastly, absolutely coast by any cops. With these monsters on you’ll be attracting everyone’s attention while you accelerate only to make yourself a target… people aren’t lying when they say these things are a major head turner.

Loudness (volume): 4.5/5
Exhaust Note: 4.5/5
Fit & Finish: 5/5
Bang for your Buck: 5/5
Installation time: About 1 hour

Question:
Do you think you’ll be getting the Roush axle-backs? If not, why and which ones will you get instead?
