GeoHot, the renowned iPhone hacker has issued a warning asking PS3 users to not to accept the update that would be given by the company in coming days. In case you don’t know, there’s a PlayStation 3 firmware update coming this Thursday that’d knock out the “install other OS” option and remove any currently-installed non-PS3 platform.

He has asked users not to update and has claimed that

He will “look into a safe way of updating to retain OtherOS support”

This is what else he wrote in his blog post

Two things, some people seem to think CFW will enable some sort of piracy. It won’t. It’ll just be a custom version of 3.21 that doesn’t lose OtherOS support. Hacking isn’t about getting what you didn’t pay for, it’s about making sure you do get what you did.

Hacker named George Hotz who is better known as GeoHot has claimed that he has fully hacked the Sony PS3. PS3 has remained uncompromised for more three years now, with a few exceptions but no one has been able to fully hack this  gaming console. In a post titled “Hello hypervisor, I’m geohot,” hacker George Hotz claimed the hacking of the PS3. But, this one pledges full read/write access to the entire system memory and complete control over the processor — all without a mod chip. This exploit supposedly “isn’t really patchable, but [Sony] can make implementations much harder.

This hacker is popularly known to the iPhone community as he jail breaked iPhone months ago and if he has done the hacking for the PS3 as well than we could see a firmware war starting and Sony is better known to knock these updates down!
