Sony has been out of the online gaming for almost 3 weeks now, and it will not be back fully for a few weeks more. They plan to have the system back online in all its (hopefully) unbroken glory by the end of the month. They plan to slowly bring things back up, including functionality such as home (really?) and chat. No word on the store and Qriocity but we should hear more soon. Most likely we will see a firmware update with the return of the PSN. Until then you can go ahead and turn your 360 back on and play games on its fully functional network.
