The games are over at 3androidapps.
Here are teh instructions and it's the last part that's tripping me up (I've bolded it)...
Download and install the Google Android SDK program and the Android USB drivers.
You need to modify your Android's settings to allow the installation of applications from other sources. Under "Settings," select "Application Settings" and then enable "Unknown Sources." Also under "Settings," select "SD Card" and "Phone Storage," and finally enable "Disable Use for USB Storage"
This last step is easy. Open Command Prompt and type the following: adb install <apk file>
So do I just put this on the root of my SD card? And does <apk file> change it from a .jar file?
