frequently-asked questions about jailbreaking.
I think it’s good for you and me to write up a FAQ. So here is the
complete guide for jailbreak iPhone. I try my best to cover all common
questions and show you all the available references in this guide.
If you’re new to iPhone jailbreaking, this guide is specifically for
you. Even you’ve jailbroken your iPhone before, I’m sure you’ll find
some useful information here. So bookmark this page. It’ll been updated
regularly whenever a
new version iOS and jailbreak guide release.
What’s Jailbreaking?
Apple’s iOS, the mobile operating
system for iPhone, iPod touch and
iPad,
is a closed system. In other words, Apple only allows users to run the
built-in applications and those applications available from App Store.
Jailbreaking tries to break this limitation by gaining full access to
the iOS. That means, with jailbreaking, you’re free to install 3rd party
applications, tweak, hacks and themes that are not available from the
official App Store.
Why Jailbreak?
There are a number of reasons for iPhone jailbreaking but let me sum up into two.
The most common reason why people need jailbreaking is for unlocking
the iPhone. As you know, in most countries, you can only purchase locked
iPhone that
works
only with a particular carrier. If you want to use your iPhone with
other carriers, you have to unlock it using unlock software. But before
you use any software to unlock your iPhone, jailbreaking is the
essential process.
The other reason for jailbreaking is you can install application
tweaks, hacks and third-party applications that you’ll never find in the
official App Store. Apple does not allow developers to modify the look
and feel of the iPhone’s interface. User are only allowed to set the
wallpaper. With jailbreaking, you can install third-party theme managers
like Winterboard or
Dreamboard
that completely transforms the look and feel of your home screen. Other
than customizing the interface, you can also install tweaks such as
Swype Keyboard,
PictureMe and
YourTube
to add functionality to the built-in iPhone apps. As you’ve gained full
access to the iOS, if you’re geek, you can even install SSH daemon that
lets you access your iPhone remotely and transfer file without
connecting to computer.
These are just some common reasons when people consider jailbreaking.
In short, jailbreaking opens lots of opportunities to tweak your
iPhone.
How do you install third-party application after jailbreaking?
Normally after jailbreaking, you’ll find a new icon named “Cydia” on
your home screen. You can consider Cydia as the App Store for
third-party applications. Just launch cydia and you can install
applications onto your iPhone. For further information, you can refer to
the below posts:
Jailbreaking vs Unlocking
Some people think jailbreaking equals unlocking. Actually they refer
to different process. As explained earlier, jailbreaking is the process
that lets you gain full access to the iOS while unlocking is the process
to free your iPhone to use SIM card from other carrries.
Jailbreaking is an essential procedure for unlocking (as it allows
you to install unlock software on your iPhone). However, jailbreak and
unlocking do not refer to the same thing.
Tethered Jailbreak vs Untethered Jailbreak
Sometimes you come across two jailbreak terms: tethered jailbreak and
untethered jailbreak. So what’s the difference? When people say the
jailbreak is tethered, this means the jailbreak is not permanent. For
whatever reasons your iPhone is rebooted, you’ll lose the jailbreak and
you have to use jailbreak tool (e.g. Redsn0w) to boot up the device.
That’s troublesome. So normally tethered jailbreak is not preferred.
Untethered jailbreak, on the other hand, is the ultimate jailbreak.
You’re free to power off or reboot your iPhone. You won’t lose jailbreak
and your device just works as usual.
Can I unjailbreak my iPhone and restore it back to factory state?
Yes, you can always restore your jailbroken iPhone to the factory settings. You can refer to the below
post for the detailed procedures:
It’s always recommended to restore your jailbroken iPhone into
factory state before you bring back the device to Apple store for
repair.
Does jailbreaking remove all my iPhone data?
Jailbreaking doesn’t remove your iPhone data. You can always restore
your iPhone data including SMS, contacts, notes, applications after
jailbreaking. However, the prerequisite is you back up the data through
iTunes before going through the jailbreak process.
If you follow our guides for jailbreaking (that are listed below), the very first step is to back up your data.
What software do you use for jailbreaking?
There are a number of jailbreaking tools that are available for free. Here are the most common tools you can use:
JailbreakMe – Developed by a famous iPhone hacker,
JailbreakMe is the easiest jailbreak tool. It is a web-based jailbreak
tool. No download or installation is needed. Just point the mobile
Safari to the jailbreakme website and you can jailbreak your device with
one-tap. However, JailbreakMe only supports iOS 4.3.1, 4.3.2 and 4.3.3.
Redsn0w – Redsn0w is one of the popular Jailbreak
tool developed by iPhone Dev Team that supports jailbreaking on iPhone
OS 3.0 or up. It supports all models of iPhone including iPhone 2G,
3G/3GS and iPhone 4 as well as iPod Touch and iPad. Both Windows and Mac
version are available.
PwnageTool – Also, developed by iPhone Dev Team,
PwnageTool is a jailbreak tool for Mac platform only. It supports
jailbreaking on all models of iPhone. Compared with Redsn0w, for which
it performs jailbreaking directly on iPhone, PwnageTool takes a
different approach of jailbreak that it creates a custom
firmware
file (i.e. IPSW) for jailbreaking. PwnageTool is considered as more
flexible as it allows the direct modification of firmware file and
preserves the baseband version for unlocking.
