Just used the guide on cyanogenmod.com to install recovery on my girlfriends legend(was stock). Did not unlock the bootloader, so it's still S-on, but this ROM is working great.
At first GPS was not working(0 satellites in GPS test), but then i read that radio version radio 7.13.35.05 should "fix" GPS on cyanogenmod.
Had to downgrade CWM to version 2.5.x to be able to flash the 7.13.35.05 update.zip, but after I flashed the radio, GPS worked immediately.
The ROM seems to be working flawlessly now, great work!
