EVERYONE STILL LOOKING FOR A LINK TO THE ZV9 UPDATE READ THIS!
The king from Virgin has been taken down, and most of the one's floating around don't work either, but it's still on the phones! I had a replacement phone mailed to me today, and found that it's in the about phone section on the stock rom. If you backup your current rom, restore the phone back to stock, and then look in the about phone section...the first option is SW update.. this is the zv9 update. Then you can go here
http://androidforums.com/optimus-v-all-things-root/531810-rooting.html to download the one click root. After that finishes you just restore your backup and your done. Although I know there have been complaints about the update decreasing data speeds, I saw a pretty significant increase in both phone reception and 3g speed. I honestly think my GPS seems to be locking in alot faster now as well. Not telling anyone what to do one way or the other, just thought I would share
EDIT: I said still on the phones... I know it's not actually on the phone, but rather still accessible through the phone... so no pm's to correct me
