First off when you run geplayer on your device you'll notice that it tells you some important bits of info right at the top (the IP address and port number). You need these to connect.
You need some fpt software, FileZilla does the job perfectly
http://filezilla-project.org/ go and download it and install it.
Run geplayer on your app, and run Filezilla.
At the top of theFilezilla screen you'll see various boxes, fill them in as follows:
Host: the IP address as displayed on your device.
Username: leave blank.
Password: leave blank.
Port: the port number as displayed on your device.
Click the 'Quickconnect' button.
You should now find that Filezilla connects to your device and shows the directory structure on the right.
You are now connected.
In Game Editor load up your game. In the file menu click 'Export', click the 'select' button and chose where you want to save your exported version of the game.
**Important: You must EXPORT your game file as geplayer.dat or it will not run.
Now with thesave location set click the 'Export Type' button and select 'Game Data Only (iPhone, iPad or game level without executable engine)'.
Now click the 'Export' button.
Now you have your exported game, and a connection to your device.
Navigate in the left window of Filezilla to the location of your new geplayer.dat file and drag it across to the right window. Your game will be copied to your device.
To run your game just click the 'Stop FTP Server' button on your device.
Extra info: When you click the 'Stop FTP Server' button the game looks for the geplayer.dat file and loads it. You can also copy other data files to your device that can be loaded from geplayer.dat, so level data, save game files etc are all fine and you can call them anything you like.
