The web store was launched in December for PS3 and Vita, but currently does not set purchases to automatically download. Firmware 4.40 also adds more system stability.
Also some wireless and wired stereo headsets are now supported when playing PlayStation 2 Classics downloaded from the PlayStation Store.
The official PlayStation website summarised firmware 4.40’s main features:
● System software update 4.40 will allow users to download content purchased from our online store to their PS3. This feature is not available yet and will be activated in May 2013. Keep an eye on eu.playstation.com for a detailed guide explaining how to make the most of this feature.
● The wireless stereo headset (CECHYA-0080 / CECHYA-0086) and the stereo headset (CECHYA-0088) now support PlayStation 2 Classics that have been downloaded from PlayStation Store.
● System software stability during use of some features has been improved.
