I found a one click method that roots, installs all necessary drivers, and puts a custom recovery on your phone that will let you back up all your info and flash custom roms. I found a custom rom that is the stock virgin mobile rom with all the bloat ware removed. None of those crappy VM apps are on the phone. When you start the phone the stupid virgin mobile splash screen and sound is totally gone. It goes from saying LG to android.
This was super easy to do. The rom has a overclockable kernal also. I overclocked my cpu from 600mhz to 760mhz and it is way smoother, alot faster now. I can text and the phone keeps up with me, even when I use swype. If interested let me know and I can post the links to where I got this info from.
