I downloaded it and had no problem at all. I would say, the problems are not update-related. If you play a lot of multiplayer or wanna download a game or a patch, go ahead. If you dont wanna do this things, you can wait.
Update, via usb storage (is always better and faster).
To do it create a folder in a memory called PS3 in that folder create another Folder called Update and download the official update in your usb.
