According to Arse Technica there are a number of bugs which the PS3 has, but Sony's version 1.11 upgrade did not seem to fix any of them.
There are a couple of threads that have opened on various PS3 message boards with the hope of trying to find the bug that version 1.11 fixed.
Apparently the Blu-ray scaling issue wasn't fixed, the browser is still slow, the store doesn't look different and there is no background downloading.
Arse did notice that there was a new account management tab, so punters can add more money to my virtual wallet to spend online without having to go to the store.
No one can believe that rather than help those people who managed to get a PS3 earlier by fixing bugs in their machines, Sony seems to just want to help them spend more money instead.
