Gotta be honest with you....I absolutely LOVE this phone and dont think I'm ever going to root it. No need...its fast as all ****ing hell and the software works great. I've been rooting flashing ROM's on my past 2 phones for years and I'm kind of over it....at least for now
Yeah the advantages are great but the cons are also a pain in the ass. Camera's that only half work, almost endless amounts of bugs, etc. Not to mention LG is rolling out JB as we speak.
As for how the phone is....its FASTTTTTT. I destroyed my girlfriends S3 in Quadrant and its eaten up everything I've put thrown at it (games, multitasking with apps, etc) with ease.
