Every since my laptop broke i've been using my PS3 for web browsing, but i've noticed a problem for a few months. Whenever I use it for internet, MB by MB get sliced off the memory of the system. Around 10 GB now are gone. I've deleted the cache, history, searches, cookies, but only a few MB come back. What's going on? Is it secretly saving info that's hidden inside it somewhere? It has only a bit over 2 GB left now.
