Wait for the damn ps3 patch. stop complaining about how xbox is getting all the attention. sure, Microsoft DOES pay to get everything first. but remember that the ps3 and xbox are 2 different consoles, meaning that they cant use the xbox patch for the ps3... Every system is having different issues.. now, can you imagine finding a fix for every single bug / glitch, making sure it doesn't cause more bugs.. and if it does, fixing that bug. geez.
It doesnt take a few minutes.

As for most of you getting a bad lag online, try checking with your internet provider (Your lag can be coming from your crappy internet connection), or check the space on your console, maybe you have used up way too much memory (happened to me when I first got Black Ops, once I cleared out all the crap I didn't need, it was fine)
