[For those not paying attention to the patent war between Apple and Samsung, Apple earlier won a preliminary injunction against the Samsung Galaxy Nexus based on a unified search patent.]
Google said that Android 4.1 (Jelly Bean) fixes the patent infringement issue which halted sales, so it was prepared to restart sales next week anyway. With the sales already re-starting, consumers are getting a few days head start.
Notably, orders made now will ship in two to to three weeks. We assume that gives Google time to get the Jelly Bean build on the Galaxy Nexus, which is a pure Android device.
Still if you want pure Android - and also Google's latest developer phone - you should order it now, while it's still available. Google's claims and confidence notwithstanding, it's possible the changes they placed into the new software build for the Galaxy Nexus might not be as issue free as they believe.
