aburton has provided a link to the korea rom of LG Eve (they call it LG KH5200 over there.
this is the link to the rom. I have managed to flash it with success to my phone. Ran it for one day and here are my results:
Better Battery Life
Youtube in HD
Google Maps Navigation
Backup your contacts (and your APNs)
XIM.apk from your current rom.

Flashing new firmware (e.g. different provider / clean version)
Download and install the LGUSBModem drivers (I used the popular 4.9.4 version - LGUSBModemDriver_WHQL_ML_Ver_4.9.4_All.exe). Do not have USB Debugging mode enabled on the phone.
Download and unzip LG-Utils-0.4.2.zip.
Download B2CAppSetup.exe (and run it, it will download the full app from LG).
Download the korean rom for LG KH5200 (V10M_00.kdz file).
Extract the kdz file to a cab file:
Run KP500-Utils-EN.exe (from LG-Utils). Windows Vista/7 users: Please run in Administrator mode)
Choose "I - Extract files from a KDZ file".
Enter the path of your .kdz file, it will produce a cab file in the same directory.
Flash the phone (turned on in normal mode, not emergency mode or fastboot):
Run KP500-Utils-EN.exe (from LG-Utils).
Choose "J - Flash with assistant (file .cab)".
Enter phone model "KH5200". this is necessary, tried with GW620 and program kept crashing)
Enter path to your newly created .cab file.
Enter new software version V10M_00
The LG flasher will be launched and should connect to the phone and do the job (it will reboot a time or two and go into emergency mode, so don't panic if you see this).
Please note that I am not responsible for anything that happens to your phone. I'm just posting my installation results.
You should have problems connecting to your 3G mobile data network.
This is because the APNs have been lost from the update.
Korea has removed the option to configure APNs in the Mobile Network settings menu.
Don't bother to add it via apns-conf.xml. It won't work either.
Instead, run this command
adb shell am start -a android.settings.APN_SETTINGS
and configure your APNs accordingly.
Note: You can use Any Cut to gain access to this menu too.
While typing a message, you may realise that the keyboard mapping seems to be wrong.
To resolve this, take XIM.apk from your previous rom and push it to your phone.
adb install XIM.apk
And yes, you will have a nearly perfect rom
