Pranay, the first (133mb) patch was the unlock for online. The second one was fixes for the online.
No game is perfect, but Gran Turismo 5 really sets the standards on how a driving SIMULATOR should be. Seeing how Forza is just an image of the GT franchise, I expect Turn 10 to learn something off of Gran Turismo 5 for Forza 4. That would be being an actual racing simulator. Games like Forza and NFS: Shift consider themselves racing simulators, yet they're arcade racers with certain simulation properties. That's where GT5 sticks out of the crowd, there's simply nothing like it on console.
