Sony have today updated Media Go, the application which allows you to download games, comics and applications to your PSP via your PC.
The new update (1.40) includes several new enhancements such as adding support for new Sony Ericsson Mobiles and the ability to download game extras and themes. Other extras include new icons and categories to enable you to organise your library better.
Perhaps the best new feature is the ability to download items from the store without hooking your PSP up to the PC.
You can download the latest update now, just load up Media Go and hit the Check for Updates button.
