Applies to most SE phones. Especially the new breeds of walkman phones, and k750i If u have an infrared, or bluetooth device on your pc, u send the files to your phone and u'll receive it like a sms. please note: unlike nokia phones, SE or at least most of them, after receiving an installation file through bluetooth or infrared, will prompt u immediately to install it. If u choose no, thinking u'll install it later, well, u cant do that, as the file will be deleted. At the same time, if u click yes, after a successful installation, the file will auto delete itself. Therefore, if u wanna transfer multiple games to your cellphone via this method, u'll have to do it one at a time. But the recommended way would be to use a usb cable, and transfer the installation files to your phone. Save it in the folder memorycard(MMSEMC or something equivalent)> media files folder > Other. Then, use the file manager to access the folder. The installation file will be there. Install, and enjoy it
