Cyanogenmod 9 (CM9) for the Galaxy Nexus has been in the nightly stage for quite some time now. Nightlies are automatically generated builds of the ROM that are built every night incorporating all the changes made by the developers every day, letting users keep up with the latest changes and improvements. However, with the Galaxy Nexus, the nightlies aren’t very regular and are infrequently built.
Keeping that in mind, XDA modder swordrune10 has taken it upon himself to build regular CM9 nightly ROMs, until the official nightlies start getting built on a daily basis. However, these builds are only for the international GSM version of the phone, so don’t try them on the Verizon CDMA variants.
