I did the one click root only a month after I bought my phone, I'm a windows guy, was very nervous about manipulating the phone in any way without knowing anything about it, in fact I'm finding learning about it so complicated, it feels like that first day I was introduced to Windows for the first time, took me years of reading and messing up my pc and fixing it to get the knowledge I have now, and unfortunately, by the time I figure out Linux and Android at a level to where I am with Windows, the Android might be absolete by then, too much info out there. So much too learn and understand, I cant take it anymore. I'm not a Dev, and suck at Programming. But I am a TechHead. You have to already understand all this stuff before understanding all this stuff. All the Devs talk like they are talking to Devs, can't understand any of them and need to constantly look up every other word on the net to try and follow along.
But anyway back to Rooting - going by the directions exactly, it worked fine the 1st time, and it allowed me to download and install all kinds of different and cool apps I otherwise couldnt use at all.
It makes the Phone so much better, gives you access the the "whole" of the phone.
The one click root thing will install superuser, after it's installed, you don't even have to mess with it really.
It just gives you Admin privelages and access, etc.
Install it, you need it:
