About JailBreaking & Unlocking – Details, Differences [iPhone, iPod]

Debajyoti Das — Sat, 28 Aug 2010 17:49:37 +0000

What is Jailbreaking ?

Many iPhone users are curious to know what jailbreaking is and how they can unlock the potential of their iDevice using jailbreaking. Well jailbreaking is basically modifying the iPhone’s firmware so that you can get access to the root of its operating system and install any application of your want. A popular application installer which people use after they jailbreak iPhone 4 is Cydia.

What is Cydia ?

Cydia (Link) is a software installer for iOS firmware that runs on Apple devices like Iphone, Ipod touch 4 , iPad. Cydia lets a user browse and download applications from their repository, just like Apple Store. It is created by Jay Freeman. Cydia has tons of apps that the Apple Store won’t allow users to download and install.

Other than Cydia, there are other installers like Installous, but they let you install cracked apps, which is illegal and we won’t be discussing about them in this article.

How is Jailbreaking different from Unlocking ?

Many people confuse jailbreaking with unlocking. Unlocking iPhone is the process of modifying the software coded restriction, which when removed enables your device to work with any carrier. iPhone comes carrier locked, with exclusive rights to AT&T in the United States.
