Just a few days after the Galaxy Nexus was removed from the Play Store following an injunction in Apple's suit against Samsung. However, as of today, the flagship Android phone is available from the Play Store again. While customers can purchase the device, the site says it won't ship for 2-3 weeks. This is in contrast to the immediate availability the device had prior to the injunction.
Update: And now the site says that the Galaxy Nexus will ship in 1-2 weeks. We're unsure what caused the change, but the net effect is still largely the same: you can't get it immediately, but soon.
It's still unclear how Google is planning to rectify the allegedly infringing features, however we know that an update is in the works. The shipping delay may mean that either Google or Samsung needs to open up each individual Nexus to update the software before they're legally allowed to sell the device.
Further confusing the matter, just yesterday, the 9th Circuit Court decided to temporarily lift the ban on sales of the Galaxy Nexus, pending a response from Apple. The court decided that Samsung had made a plausible argument for why the ban should be lifted. This isn't the end of the story, but it may mean that Google and Samsung are allowed to sell the device after all, update or no.
In any case, if you wanted a Galaxy Nexus from Google, you likely won't be waiting too much longer.
