It's really very simple to pass a computer game for a Sony Ericsson, the hint that come to pass has been successfully tested in the models: K750i, W800, W810, K790i, K800. I believe it should work on all models that have a file manager equal or similar to the models mentioned above.
First connect your phone to your computer.
Copy the game you want to install to the "other" phone (to do this using the Sony Ericsson File Manager).
On the phone, go to the folder: Menu \ File Manager \ Other. The copied file in the above step should be within that folder.
Therefore, to install the game / application just select it and click on "install". The rest of the process is almost automatic, you just select the folder where it should be installed.
To install themes the procedure is the same but instead of putting the file in the "other" copy to folder "themes".
As a bonus here's a batch of free games!
