Happy 4th Birthday Callie!
Unfortunately for those who chomp at the bit to see whats coming up next from Amazon's Appstore for free, you get Angry Birds Rio. Since the stores launch a couple weeks ago, AB Rio has been offered up for free. That in itself was a surprise given that Amazon advertised the little big title as free for the first day only. So this day may mark the end of that deal.
If you haven't already picked up Angry Birds Rio, do so. There is a countdown clock, and I'm not a betting man, but if I were my money is on that this is the final day it'll be offered for free.
