Sony released another firmware update for the Sony PS3 today. The newest firmware carries the version 1.32.

The Japanese Sony PS3 firmware page says that 1.32 is improving the network performance of the system software. Maybe they improved the slow browser. That would be nice a step forward.

Apparently Sony is not incrementally updating the PS3 firmware as I am still downloading, or they fixed more things.
