If you were thinking about shelling out some serious jing (translation: spending a lot of money) on one of those new 32GB microSD cards, you might want to hold off for a little bit. Google confirmed to CNET that Android can't actually format a card that big, which could lead to some trouble. The good news is that a fix is on the way and "will be part of our next over-the-air update." Google didn't say when that might be. [CNET]
Update: Yes, folks, let there be no confusion: You in fact can use a 32GB card. Never said you couldn't. You just can't format it. It's not a huge deal, but it's something that needs to be fixed.
