So, what is the jailbreak? is that Safe? Legal?
Jailbreak is the process by which a device is modified to allow unsigned code to be run.
In a more technical view, is a process where the firmware is patched to allow access to the device filesystem, then some applications are automatically installed (like Cydia or Icy), and that allow you to install new applications via an apt system ported to the iPhone.
The iPhone is running a modified version of the OS X which is already based on a BSD Operating System, therefore porting applications developed initially for Linux or BSD becomes easier.
On a jailbroken phone applications like a terminal, an SSH server, and even Java can be installed.
Also since there are no Apple restrictions developers can make better applications that can do things that otherwise it would not be possible.
So, Is it Safe?
I would say it’s completly safe, because you are modifying the software, not the hardware, of course that Apple will say it voids your warranty.
Since is software what we are talking about, you can always use iTunes to restore your factory settings.
And, is it legal?
I’m sure it is. Let’s compare it with a car:
If you bought a car, can you modify it’s engine to perform better? can you put a better sound system? can you paint it of a diffrent color?…. well it’s pretty much the same, of course if you modify your car you will for sure lose your warranty, well that’s the same for the iPhone.
And remember that anyway the only person responsible for your device, it’s yourself.
