You've got the recently released Angry Birds Lite Beta and Fruit Ninja games installed on your HTC EVO 4G, right? Then head over to Android Market to download the new updates for both apps. Version 1.3.5_beta2 of Angry Birds now runs reliably on the EVO (no more rebooting the phone or pressing the screen while the game loads to get it working), while version 1.3.1 of Fruit Ninja now includes SD card support.
I don't remember moving them manually, but both games currently appear in the "On SD card" tab in the Applications settings on my EVO. They're fairly large files, as you know, so they would've ended up on the card (I'm using a 16GB one now) anyway.
Thanks to everyone who sent this in!
