Yes this is my question as well. Since the privacy patch I can no longer update from my PS3. I patched the firmware except for the .net and one with all patched. Turns out most of the data is sent to the .net so not blocking it is kinda useless so I want to go the route of updating all my games this way. I went and updated all my 3.50+ games before downgrading back to 3.41 so I can use my E3 device and now I need to find a proggy to update from my internal HDD. Unlike most warez kiddies I have legit games on my HDD of my PS3 and don't have images on my PC as well since I saw no use in taking up so much space on my PC as well.
