Hi guys i jave a Sprint SGS4 which i was reading can be unlocked and rooted.

My phone info is as follows:
-------------------------------
Software version
L720VPUFNAE

Hardware version
L720.08

Android version
4.4.2

Baseband version
L720VPUFNAE

Kernel version
3.4.0-481102

Build number
KOT49H.L720VPUFNAE

Secure boot status
Type: Samsung

Security software version
MDF v1.0 release 2

Model number
SPH-L720

ICCID
unknown

Device status
Official
---------------------------------

So my questions are as follows:
1- how can i SIM unlock my US Sprint SGS4? If possible can you provide a step by step or link to a guide?
2- which 1 must be done 1st, unlocking or rooting, or it doesnt matter?
3- is it possible and how can i root my phone in a safe way? is there a guide to return back to stock?
4- what or which is the best and safest/stable custom recovery?

If you guys need more info about the phone feel free to ask, i will reply as soon as i see the question. Cause i have been looking all over the net for this info/guide but could find anything conclusive cause it all point to a firmware my phone doesnt have so i dont know what to do and theres an OS update pending that i dont want to install yet which i think is 4.4.4 at the least.

Thanks in advanced, and have a nice day!
Hope to hear answers and guides and links soon.
