It looks like the folks over at XDA were able to grab an “evidence” of Android 4.1, masquerading as Jelly Bean. Rumor has it a couple of days ago that Google's Nexus tablet could be the first to run the aforementioned Android OS. Of source, folks haven't really figured out if it's Android 4.1 or 5.0. But with the Google I/O commencing next week on the 27th of June, it is the talk of the town for the moment.
Apparently an XDA member was able to grab a screenshot showing Android 4.1 sporting the name Jelly Bean when he was reportedly trying to compare the price of the Samsung Galaxy Nexus on Google Play.
