Distinguish Root, Jailbreak and Unlock Bootloader Unlock Sim

Compared with computer, phone and tablet devices are relatively close. Jailbreak, root and unlock (unlock) is the way to overcome our limits, doing things that carriers and manufacturers do not want us to do.

The concept jailbreak, unlock root and is now no longer new, but still there are some people out there are inaccurate or vague about their differences. The following article will explain the differences between these concepts.

Jailbreak

Jailbreak is the process of removing the limitations applicable to manufacturers equipment.Jailbreak mostly done with devices such as Apple's iPhone and iPad. Jailbreak Apple removed the restrictions in place, allowing you to install the software of third parties outside the app store App Store of Apple. Through jailbreaking, you can do things like change the browser default email software or iPhone. In other words, jailbreaking lets you use the Apple software does not allow on your iPhone or iPad.

Jailbreak can be done also with other devices with similar objectives on the iPhone or iPad. For example, jailbreak tablet Microsoft Surface RT lets you install the computer software programs are not allowed to use. (By default, the desktop mode devices running Windows RT only be allowed to run some apps written by Microsoft, such as Microsoft Office). But note that the computer applications that have been compiled (compile) for ARM processor platform, so you can not run Windows software currently on the Surface RT tablet.

Companies like Apple and Microsoft do not want you to jailbreak their device to change the default program to run on the operating system or applications of third-party computers on Windows RT.To perform the jailbreak, hackers find vulnerabilities must turn allows them to "exploit" the device over the fence and protected by the manufacturer.

Android allows users to install apps from third party app stores outside of the Google should not need to jailbreak.

Root

Root is the process for root access (root access), giving the user full control and access to thesmartphone or your tablet. This action is mainly done on Android devices, but can also perform root on other devices use Linux as the operating system Symbian has Nokia's untimely death.

Similar to jailbreak iOS devices, root is the way to overcome these limitations by the manufacturer or network launched with Android devices. After a successful root, ie you have root access is available, you can remove or change the applications and settings on the smartphone or tablet.

One of the most common reasons to root the phone instead of the operating system manufacturers by providing a custom ROM (custom ROM) other. A custom ROM is here understood as the OS version by the programmer or programming team to develop a template for any phone. In addition, the root machine also provides the ability to remove apps not want that producers and networks put in, thereby helping to increase memory storage capacity.

Android phones root process depends on each device, but have in common is increasingly simple.Typically, the more people use phones like Nexus 4, Galaxy S3 or HTC One X will have to choose a ROM so they are more application developers are interested.

Note that root can affect product performance warranty. However, the root of the manufacturer's original ROM can now be returned to its original state pretty easy, does not affect the warranty rights.

Unlock Bootloader (unlocked bootloader)

Literally, the bootloader code is executed before the operating system starts booting. Every Android phone has bootloader to instruct the operating system to boot normally. Usually locked bootloader on Android devices because the system even though it is open source, but manufacturers still want to create the Android OS version for your device. To protect the operating system Android version of its own, the manufacturers usually locked bootloader. With the locked bootloader Android devices, machines can only boot into the ROM specified by the manufacturer. So, if you want to root your phone to install the ROM, you have to unlock the bootloader of the manufacturer.

However, note that unlocking the bootloader will void the equipment warranty. In addition, it also clears the data in the computer, including applications, gaming, SMS and MMS.

Unlock bootloader may require exploits. However, some manufacturers like HTC and Motorolathat allows users to unlock the bootloader on some devices, but warned that this would affect the rights of warranty equipment. According to experts, unlock the bootloader on the Nexus devices easier than other Android devices.

In theory, the unlocked bootloader also allows for the installation of the Android operating system is not on the device. For example, you can install Ubuntu OS or WebOS phone on the Nexus phones have unlocked bootloaders. Even Ubuntu version for your computer and can be installed on Nexus 7 tablet. Of course, the operating system must be built to be compatible with the installed equipment.

Unlock phone

The phone is sold with a service contract of the network often "network key". Network Locked means that the phone is set to only be used on a network of suppliers, for example, the iPhone version of the network lock is only used Viettel Viettel SIM is not used or SIM VinaPhone MobiFone. If you put another network's SIM in, you will get notified locked phone can not be used with this SIM.

Unlocking (unlock) the phone allows you to use the SIM of another network. To unlock the phone, you need the unlock code. Many operators are now charging to unlock the phone in case the phone network lock is still time contract with the network.

(Analysis) Android over Apple in tablet market

According to information from the data analysis organization IDC International (International Data Corporation), the number of tablet products are sold in the first quarter of 2013 increased 142.4% to more than, equal to 49, 2 million units in sales for the entire first half of 2012. In particular, not to mention the largest number of contributions from the company's products Apple with 19.5 million units, more than 18.7 million units, compared with estimated. According to the police boss apple defect is itsSamsung (8.8 million), partly due to the rapid development of the reputation of smartphone products.The next ranking of the ASUS with the Nexus 7 was released at the event Google I / O last year, Amazon's fourth and first time in history, Microsoft entered the tablet list of great success thanks Surface product line.



However, standing in another aspect, the number of products sold on the tablet market also indicates the superiority of Android tablet products from Apple's iOS. For the first time in three years, since Apple invented the modern tablet first Android sales (56.5%) surpassed Apple (39.5%), an exchange item.

Charts - Market share of the tablet you I/2013

Prestigious Forbes Magazine has launched a major cause of the market changes include:

• The tablet product has been used for more than one role in multimedia devices.
• The Android operating system has more complete level.
• The boom of Samsung.
• The "democratization" of the tablet product.

Days ago, the iPod or iPhone products and later the iPad, users will have to connect to iTunes to import and data connectivity, as well as customize their devices. From there, the app store App Store is on a strong and rich, with a full range of products dedicated to tablet devices. However, all the above operations are inconvenient to bring a certain number of users. 
figures indicated on the diagram Purpose tablet shows that tablet users used mainly to convey information via email, web, social media (mass communication method) ... While Apple products have some difficulty in accessing software content. Tablet apps for work also accounts for a portion of the graph, and in this case, the utility between Apple and Android is bringing the same.

Chart - Purpose tablet

The aim is to use the second-largest in the chart indicates that the media and entertainment applications. In fact, Apple has a more favorable starting point in the entertainment, with a wealth of game applications richness and diversity. However, there are still other applications, such as eBooks and music are available on Android devices with huge storage from Google Play, Netflix, or Amazon.Also not to mention many of the game is no shortage of products on the operating system, although it may not equal the number of products on stock iOS game. 
Otherwise, Android has really developed, especially on the tablet product line. Android 3.0 Honeycomb operating system 2 years ago and error rather weak, however, to the present time, the version ofAndroid 4.2 has been equipped with a full range of functions and works very smoothly. Furthermore, through a survey of 25,000 people showed that Android users love and are satisfied with the operating system they are using, like what iOS offers its users. 
Much everyone said that the operating system is an important factor in choosing a technology product, in which more than 50% of the fans of the iOS and Android operating systems will greatly appreciate your operating system are using. Even the number of people satisfied with the Android product is higher than Apple. This is especially true for product configuration terrible ownership, affordable price as the Nexus 7.

Charts - The Importance of the operating system when choosing a smartphone product

Here is one more factor can not fail to mention. It was the success of Samsung. At the CES event in 2011, the first appearance of the line performance devices Galaxy with the aim of competing with Apple's products from the iTouch and iPad. Samsung products are varied in size and design. Korean phone manufacturer has products precocious 7-inch tablet and a pioneer product line called "phablet" (a device with 5 inch size - owning both the characteristics of an electric great phone and a small tablet). Although surveys have shown that the Samsung brand is not comparable to Apple, but thanks to the relentless marketing campaign, Samsung has become one of the largest corporate spending for technology products in America. Now, the name associated with the Android Samsung and became two of the most famous brands in the world.

Another reason leading to changes in the balance of the market, which is the cost factor. Apple has been referred to the phone company known for high quality products and vehemently opposed production line small tablet. Meanwhile, other manufacturers have "democratize" the business by dominating the mass market with own products affordable. A recent article Android.vn haveemphasized various elements of the Android operating system . Accordingly, the list of products the most popular tablet on the market, as of 05/14/2013, including the Kindle Amazon's 7-inch, Samsung's tablet products with prices from 179 - 229 USD , and even the 8.9-inch Kindle tablet only 269 USD, cheaper than from 100-200 USD over products of Apple. The statistics also indicate that the product runs Android tablets range from 100-200 USD and 30% of the tablet market. That's not a bad figure. 
Obviously, at the present time, the tablet market is becoming a fertile market, a completely different story as what the PC market has experienced. The growth was found with a lot of diverse brands, from Samsung, Asus / Google, Amazon / Kindle with a full range of prices and different configurations. Both Apple and Google are doing well their role in the creation and direction for their own platforms. Finally, people are still the most profitable customers and consumers worldwide technology.
