view story

http://androidforums.com – hey fellas does anyone happen to know of any custom roms for a LG L38c optimus dynamic? I've looked alot and can't find any. I've read that the cryogenmod for the LG L3 will supposedly work case the hard ware on both devices is almost identical. if I install it and it doesn't work can I use cwm to restore my backup? thx (General)
