[quote name='A Happy Panda']Here's hoping AT&T and Motorola can get their shit together in time to allow side loading on the Atrix before PvZ comes out.
So many apps and games missed out on because AT&T was too stubborn[/QUOTE]
You can "buy" the app through Amazon's website and download it whenever you want, or in your case, whenever AT&T resolves their issues. I've been "buying" every single free Droid app on Amazon.com even if it's worthless garbage just because it's free. I actually install an app every now and then if it's really nice and useful/fun to me, but the rest just sit in my Amazon account if I decide to install sometime in the future.
Consider it like iTunes where once you buy an app, it's yours to download again and again in the future. So you don't need to miss out on a single free Droid app, just go to Amazon.com on a web browser (the browser on your droid phone works too) and navigate to the droid marketplace and click on buy for their daily free apps and you're set!
