Did you miss the offer of a free copy of Jetpack Joyride back in October? You have another chance to avoid the exorbitant 99-cent price, and you don't even have to go through Facebook. Free App a Day is featuring Halfbrick's coin-grabbing test flight, so you can just go into the App Store right now and download it at no cost.
To be absolutely clear about it, you should go get this free game. We were quite fond of it even when we thought of it as a 99-cent game.
