Not sure if this is the correct section, but what is the point in jail breaking your AP(Android Phone).

Jailbreaking is a term used to describe the removal of certain restrictions put on iOS devices. Before that it was used for UNIX systems (see https://en.wikipedia.org/wiki/Chroot). A jailbreak consists mostly of modifying the fstab file that controls the read/write permissions to the system partition. The end result is that the user is able to freely access the system partition and all of the files in it with rw permissions.

On Android it's called rooting. Rooting is a little different and generally not needed unless you intend on running certain applications which require root. I suggest that you do not root unless you know what you're doing (as in you've managed other Linux systems as root before). There are different kinds of root as well. Temporary root means that you'll no longer be rooted after a reboot. Permanent root means that it's persistent across system restarts. Systemless root is available too (as provided by SuperSU) and is a bit more complex.

Then you have bootloader unlocks. The bootloader is deeper than the userland/kernel that you'd be modifying with rooting. Your operating system which consists of the kernel/userland and some apps is signed cryptographically. This means that the key is checked by the bootloader at boot. Rooting and running things as root user or modifying your system partition in any way on some KNOX enabled Samsung devices will invalidate this chain on trust and result in a non-operational device. A bootloader unlock will shut off the signature checking and allow a custom operating system to be installed. Really anything with a Linux kernel will do, since that what Qualcomm, HTC, and (I think) Samsung bootloaders are set to search for.

For more info on availability of tools to root or unlock the bootloader of your mobile, search the model number on XDA.
