I have a W350i as my phone, and to install games, I usually connect the phone to my PC by using the USB cable (no software from disc required, just choose for USB mode on the phone). My phone created it's own .jad files for installation based on the game's content and the phone's software, so I only copy the .jar file in the root directory and it'll install the game after opening it in the phone's file manager. At last it prompts where to install it, either the game or apps directory.
All games installed this way have to be license free, you can torrent kind of any game like this. Hope it helps.
