A patch has been released for PlayStation 3 users of Grand Theft Auto IV. You will be prompted to download the update the next time you load GTA IV whilst being signed into the PlayStation Network. While download and installation is required to continue playing the game; totaling 18 MB, it shouldn't keep you away for too long.

As for content, the patch addresses certain online issues related to GameSpy's servers being overloaded. Not surprising, considering the sheer number of those playing the game.

Rockstar Games has released a GTA IV patch for Playstation 3 today that prevents GameSpy’s servers from being overloaded and therefore reduces the impact on those servers that were causing the game to stutter and lock up. We continue to monitor the performance of the game both on and offline and will provide further updates as necessary. We want to assure everyone that, together with our hardware partners, we continue to strive to give our fans the best possible interactive entertainment experiences possible. This update will ensure that everyone will experience Grand Theft Auto IV the way it was intended. We apologize for the inconvenience this has caused.

Results so far appear to be mixed, if discussion on our forums is anything to go by.
