Hello there
just as I wrote in the title I've been away from the Jailbreak scene for a while.
My playstation 3 is a slim model, currently equipped with Waninkoko V2. Firmware 3.55.

I would like to know if there is a better Jailbreak that I could currently apply, and any links to it.

I also heard sometimes about a double boot firmware. Still an utopy?

Thanks anyone in advance.
