You need the disc every time you want to play the game in the PS3. The game disc does not transfer to your harddrive and merely builds a file to store information that can not be put on the disc the can not be rewritten by the PS3. The Games upgrades are also stored in the harddrive file
yes you do
on the ps3 console in the front their is a button it will take the disk out
Only the Blue Ray disc drive that is part of the PS3 Game Console
The standard size disc for all Blue ray DVD and Cds will play on a PS3
Yes, usually an old PS3 disk should work on a new PS3 console.
I don't think so, i believe that it has a disk drive.
Formatting your hard disk for the PS3 will erase everything on it. If you are adding a hard disk to your PS3 it will prepare the drive for the system.
This happened to me too! Turned out it wasn't the ps3 it was the disk.
you need to update the system. then it will install the new update. or it could be the smudges on the disk
No, you cannot upgrade the software on your iPod touch using a PS3. You need a computer.
You jailbreak the firmware.
No the game discs do not download and need to be reinserted each time you play. Some information is downloaded, but not enough to let you not use the disc
