PS3 System Update Suggestions

I just bought my PS3 and I love it. I think it's great and I am happy even just playing the demos LoL. Anyways on a serious note, I thought it'd be great to just start a thread where we can suggest useful things that can/should be included in the next update (or future updates). Not sure about Sony, but if some developers roam boards to see what customers want, this might be something beneficial for all of us and furthermore we could discuss some of the features we post here to see what's best/importabt.

IF THIS HAS ALREADY BEEN POSTED - please lock it thanks. And please,please try to stick to the topic thanks.

Suggestion: Being able to use pictures to set your own wallpaper background.

Reason: Just cos I think it's cool although i guess it depends on what wallpaper u use, cos with my 360 it makes things difficult to see and the same can be said with the XMB.

Priority: Low

Suggestion:  Update compatbility list for say GT4

Reason: Self-explanatory. I guess this will also update compatability all across the currently not working list. But I was smiling to myself when I could run FFVII on it.

Priority: Low but I don't know might be Medium to High as well.
