Re: Jail Breaking, What Does This Mean?

2012-06-11 Thread Christopher Chaltain
It's true Android is more open than IOS by nature, but you still have to
"root" your Android phone, which is analogous to jail breaking your IOS
device, to get root privileges.

Also, although the openness of Android allows for more innovation and
creativity, it also permits more fragmentation. I think individual
carriers and even the Android ecosystem as a while will begin to address
this though.

mine, not yours.  What I did gather is that when I get an IPhone, I will 
leave the doing of such things to others, and just take what Apple allows me

though I am leaning toward an IPhone at this time, I do believe that, within 
a little while, android is going to give the IPhone a really serious run for

...And if I was a total non-techy, the below message would have made me 
run away screaming, and never want to jailbreak. . Seriously 
Joseph, sometimes you have to keep it simple, sort of like on the 
Braille Sense list. In short, non-techy terms, jailbreaking allows you 
to add tweaks or features or abilities to the iPhone which normally 
can't be done.

Hi,
To explain jailbreaking, I think we need to visit operating system
security and user levels.  But first:
Yes - jailbreaking and unlocking are two different things. Jailbreaking
means using some OS exploit to run programs using a different user's
privilege, whereas unlocking means allowing a device to be used on any
carrier (as many phones are locked to specific carriers).
Now onto the subject at hand:
There are at least two user modes under Unix (which is the basis for iOS
and Mac OS X and other OS's such as Linux): root and normal user.  The
root is the user which has total control ovth files and programs on
Unix, such as program installation, file system modification and so on.
Many Unix systems run in normal user mode for most of the time - and iOS
follows this.
Under iOS, there are two users defined (although it may not appear to be
so): root and mobile.  Root is the admin account while mobile is the
regular user mode of the iOS.  What dailbreak does is it changes the
running mode of the iDevice to that of root mode where the device user
has total control over files and programs on an iDevice.  This allows
installation of apps not authorized by Apple and to perform other things
such as modifying how the device works by using tweaks and changing files.
But you may ask, "how can I access my iDevice from my computer?" This is
where SSH (Secure Shell) comes in.  This is a terminal environment where
a computer can access another computer over it network.  A good example
is remote website administration from a home computer.  In order for
this to work, the target device must be told to accept "incoming" SSH
connections (in this case, by jailbreaking it and installing OpenSSH).
 From the local computer (the one which will be accessing the iDevice),
the user needs to know the IP address of the iDevice, its root userdayn
and password (by %default, it is "root" for user"^n and "allpine" for
password; it is recommended to change the password).  Because we're
using root user mode,
be careful about what you do with file system in iDevice - one wrfg
change and it requires restore via iTunes, which installs "regular"
firmware instead of jailbroken firmware.
Finally, let us investigate how jailbreaking is even possible. Operating
systems, like any programs, contains well-known bugs and opportunities
for programmers to mess around with it (at least through bugs and
programs).  For example, there was a bug fix release by Apple last year
because some PDCF documents made the device unstable, which was used by
jailbreak programmers (this is callbed "exploit," that of using a bug to
mess around in an OS).  So in order for jailbreak to work, programmers
need four things: the exploitable bug itself in a device firmware, a
modified firmware that allows root control of a device, a way of
transfering this new firmware and making it permanent (called
"untethered jailbreak").  First, the programmers find out the exploit in
a firmware, prepares a new (modified or unlocked) firmware that be^akes
advantage of the exploit and makes it availible to others.  Then the
jailbreak package connects to the iDevice (mostly via iTunes connection)
and embbeds the newly modified firmware to the device's memory.  Then it
does some modifications to make this patch permanent unless restoration
via iTunes occurs, at which point the jailbreak will be undone by
flashing the
official firmware from Apple.
Hope this helps.
Cheers,
Joseph

H, to answer the other question, jailbreaking and unlocking are not the
same. Jailbreaking is getting out of the sandbox experience and allowing
you to add tweaks or other apps which Apple normally doesn't allow. It
enables you to do cool things with your phone which you can't normally
do. Unlocking makes your phone usable with other carriers like T-mobile.
You can jailbreak without unlocking and you can unlock without
jailbreaking. Or, you can do both.

Jailbreaking is not illegal however it will void any Apple warranties 
you have. But it is certainly not illegal. SSH I think allows you to 
securely connect to a remote machine.
