Yeah I agreed, but how would they manage to do this?
If you don't play the game online or connect to the internet and do not sign into the PSN store while playing the game then they won't know about it. I am sure that XBOX 360 users got banned because they are playing the game online. I'm not going to get another PS3 lol, I don't even have space to put it on my desk. All the precious space is belonging to my Rare species 60G PAL PS3. I dedicated all the free air flow and constantly wiping it with the microfire clothe to keep the dust off it.

I would consider buying another PS3 only if it gone below the 250NZD marks. Buying another PS3 is more expensive than buying the game

I've been using homebrew on my PS3 for over 2years now (to Play PS2 backup games) and Sony didn't really do anything to it .
The reason is obvious that Not many people have access to get it to work, but this Jailbreak is a serious new threat to SONY. They have lost billions on promoting and selling the console since launch. But they are starting to making a bit of profile to recovered the lost and yet this hack is found during the time that they are trying to regain the stability in the industry.

GT5 is going to be sick, but this jailbreak will deappreciating the work of the GT5 developer, they spent over 5years to make this game. I actually preorder this game without hesitation, because I think Polyphonic deserves my hard earning cash. Even though it's quite over priced in New Zealand.

On the other hand why don't we just buy another HDD and do a hot swaping whenever we want to play stuff online

If the jailbreak installed game onto the internal drive, then why not swap it with another one? one for offline and one for online. Back up the setting and restore it to each hdd

So we have 2 version of HDD to use for 2 occasions.
