New firmware is available for PlayStation Vita. Update 1.69 is entirely optional to download, and according to Sony’s Eric Lempel, it’s designed to “[improve] software stability.”
Update 1.69 is 97 MB in size and should download fairly quickly. Remember: if the update is going slowly, you can always attach your Vita to your PlayStation 3, which should let it download faster.
Other than improving “software stability,” does Update 1.69 also open the door for new additions promised soon, such as YouTube and PSone Classic support? Only time will tell!
