This is the best ROM till date for the Optimus One. Mik OS is a legend.

This is a Gingerbread Custom ROM but works only on phones withe the old baseband(the phones which were updated to the official Gingerbread ROM by LG have new baseband). SO the unlucky people will have to flash the old baseband.

Enough of my talking. The full info about this ROM can be found at – http://forum.xda-developers.com/showthread.php?t=946354

I uploaded the file to iFile.it. No waiting time and blazing fast download speeds.
