My husband and I have identical Droids, purchased together 9 months ago. Mine has been giving me regular update notifications, which I install, and my Maps module is presently up to version 4.6.0. His has given him system updates, which he has installed, which puts us both at System 2.2 and no more updates available, according to the phones. But his Maps app has never updated (and no notifications have appeared), and it is still at the version 4.3.1 it had when we bought the phones. How do we get the new version on his phone?
