The only rom for the optimus v is aosp. It isn't listed for the v, but is listed under under the optimus one. For now I would suggest staying away from Rom Manager. As you can tell, our phone is not fully supported yet and most of the roms for our phone will probably never be supported by Rom Manager. Just make sure any thing you download through it is specifically designed for the optimus v. Installing a rom for a different phone will most likely result in a nice pretty paperweight.
