PS3 firmware update 2.35 improves stabilty of some PS3 titles... but not GTA IV?

Today Sony released firmware update 2.35 for the Playstation 3, the minor update according to Sony fixes stability to several PS3 games. Considering Rockstar's announcement about the freezing problems in GTA IV being Sony's problem you would think this patch would solve the issues.

Unfortunately so far there appears to be no change, however Sony have said that they have identified the issue and are working on a solution. So maybe in the next one?
PlayStation 3 firmware update 2.35 is now available. According to the US PlayStation Blog, v2.35 is "a relatively minor update to improve stability of some PS3 titles." We're willing to wager a handful of stolen cars that "some PS3 titles" is a better way of saying Grand Theft Auto IV
