Well, now we have proof in form of a screenshot linked to a purchase for the Galaxy Nexus HSPA+ device via the Play Store. As you can see, it clearly shows a small little tid bit of information that makes everyone assumptions truth. You can see it lists Android 4.1 Jell…. Jelly Bean. It is great to finally have that mystery solved. It does however, create more questions. It mentions ‘soon the first phone’ running the new OS. Interesting to note the mention of this on the HSPA+ version of the device. In our eyes that means Verizon is pretty much out of the loop at first, if not entirely. It also implies that Jelly Bean will be an update and not accompany a new phone launch. Not that it is a big issue. It should also put Google in line to launch the Nexus 7 tablet with Android Jelly Bean as the first tablet though and we should be seeing that at Google I/O, we hope. Now, when is the update going to start hitting devices and when will it land as open source for the developers. If it is announced at Google I/O we expect it to be starting pretty soon.
