I confirm is working on my LG P500 also!
I made a downgrade a week or so to 2.2 and rooted the phone with z4root!
However, I made a official update via LG Utility and my phone went back to 2.2.2
I lost root privileges as I expected.
Rooted again with GingerBreak-v1.10.apk and everything is fine now.
I also installed a custom kernel (milk-desktop #36) to reduce the lag when typing on screen!
Thank you very much!
