Well, it looks as though Android 4.1 is destined to be the deliciously-named Jelly Bean OS from Google, thanks to a Google Play listing for the GALAXY Nexus that has since been removed. Droid Life took a screenshot before it was removed, thankfully.
The next thing we need to know is will Jelly Bean be shown off at Google I/O next week? I really hope so. Droid Life have noticed that during the checkout, the new thumbnail shows a picture of teh device with the new glassy Google Search bar, which teases us that little bit more.
We should have more details of Android 4.1 Jelly Bean next week during Google I/O, hopefully.
