As you may know AT&T have blocked sideloading on the Captivate, but there is a way around that (Sideloading Wonder Machine). However, because of this, there is no version for the Captivate that can be downloaded from Gameloft's site (Gameloft won't put their good games on the Android market). I have tried using another version, the Vibrant's unless I'm mistaken, but it would not download the extra data using my wifi. I do not want to use half of my data plan on something that might not work, especially a demo. How did you do it?
