Can you believe it? The App Store hit 500 million downloads just three months ago, and Apple’s already counting down to 1 billion. Crazier still, they’re giving away free stuff to celebrate.

It’s pretty easy—download any app from your computer, iPhone or iPod touch and you’re automatically entered to win. Every app download counts as an entry, though you’re limited to 25 entries a day.

The prize package includes a $10,000 iTunes Gift card, “fully loaded” MacBook Pro, 32GB iPod touch and Time Capsule. Which is actually a really conservative prize package—worth around $14,500. You only turn 1,000,000,000 once, and they’re celebrating in style.

With only about 70 million apps to go, we’ve got less than two weeks before the big 1-0 (0-0-0-0-0-0-0-0-0). What are you going to download?
