The Iconia Tab A500, Acer's "better choice" tablet, is set to join the ranks of Android 3.1 slates on the 5th of July, according to the company's German Facebook page. That's a little later than the June timeframe we'd initially been promised, but the precision of giving an actual date this time around inspires confidence that the OTA goodies will indeed be delivered. So far, we've only seen Acer announce this news on its German portal, so please keep your optimism in cautious gear if you reside outside the Bundesrepublik. The only certain Android update is the one that's already on your device.
