After Apple won the injunction against Samsung, Google and Samsung needed to freeze the sales of the Galaxy Nexus. So they did. Google pulled the Galaxy Nexus from the Google Play Store, but the price remains and there’s an option if you want to receive a notification when it’s available again.
Google is hard-working to clear the ban and bring their device back to the shelves. They say it will be available as soon as next week. So, if you were planning to get one, you’ll have to wait seven days more.
