The EFF otherwise known as the Electronic Frontier Foundation, is always fighting for the little guy, their latest campaign is to get Jailbreaking of all devices seen as legal, this of course including the PS3, here is a quote from the source:

The Problem – Smartphones, tablets, and video game consoles are powerful computers with lots of untapped potential. Yet many of these devices are set up to run only software that’s been approved by the manufacturer.  Modifying a device to run independent software – known as jailbreaking – is important to programmers, enthusiasts, and users. But jailbreaking creates legal uncertainty. Some device manufacturers claim that jailbreaking violates Section 1201 of the Digital Millennium Copyright Act (DMCA), which carries stiff penalties.

The Solution – EFF is asking the U.S. Copyright Office to declare that jailbreaking does not violate the DMCA, and we need your help. In 2010, the Copyright Office said jailbreaking smartphones doesn’t violate the DMCA.  This year, we’re asking them to renew that exemption (otherwise it will expire) and expand it to cover tablets. We’re also asking for a new exemption to allow jailbreaking of video game consoles.

How You Can Help – The Copyright Office needs to hear from people who depend on the ability to jailbreak to write, use, and/or tinker with independent software (from useful apps to essential security fixes) for smartphones, tablets, and game consoles. You can submit comments online at this link.

Here are some questions you might want to address in your comments:

1. Which jailbreaking exemption are you supporting—smartphones/tablets, video game consoles, or both?
2. What’s your background (i.e., are you a developer, hobbyist, academic, independent researcher, user, etc.)?
3. What device do you want to ensure you have the legal authority to jailbreak?
4. Please explain why you want to jailbreak this device. What limitations do you face if you aren’t able to jailbreak it? Is there software you couldn’t run, computing capabilities you wouldn’t have, cool things you couldn’t do, etc.?
5. If you’re a developer, did an online application store or console manufacturer reject your app or game? If so, what reasons did they give?
6. Is there anything else you want to tell the Copyright Office?

Concrete examples will help show the Copyright Office why they should renew and expand the exemptions for jailbreaking. Send your comments to the Copyright Office athttp://www.copyright.gov/1201/comment-forms/. Where the form says “Comment number(s) of proposed classes of works to which you are responding,” enter a “3” if you’re writing about game consoles or a “5” if you’re writing about smartphones or tablets. You mightconsider also entering a “4″ to submit your comments in support of an exemption request proposed by the Software Freedom Law Center to allow jailbreaking of “personal computing devices.”

Comments are due by February 10 at 5 PM Eastern Time. After you send comments to the Copyright Office, please also send a copy of your comments to dmca-comments@eff.org so that we can see what people are saying.

We also encourage you to sign this petition.

This morning KaKaRoTo announced on his twitter that he has jailbroken OFW 3.73. There is not much information available yet about this jailbreak but he already stated that this is no CFW and doesn’t allow backup managers to run. But it should allow you to run your favorite homebrew and still play the latest games. For people who are not aware who KaKaRoTo is, he is the person that released the first CFW ever for Playstation 3 and always released his methods and software.

And it looks like everyone is in luck because KaKaRoTo is planning to release his work and method (as always). But we all have to wait for a while because according to KaKaRoTo it won’t be out in the next two weeks and there is still some work left to do.

[07:28:39] <KaKaRoTo> heri, docpaul showtime would work fine
[07:28:58] <sandungas> kakaroTo, this means new tcl patches for mfw and some changes to manage 3.73 ?
[07:29:17] <KaKaRoTo> ddoo, and no I didn’t fix the npdrm algo, that’s what I’m missing (hence the “kind of”) but I’m not
working on that, that’s someone else’s job
[07:30:05] <middleman> gonna debut it at ccc kakaroto or before?
[07:30:06] <KaKaRoTo> ddoo, and even if npdrm signing worked.. how do you install your pkg on an OFW 3.73 ? :p
[07:30:22] <heri> so KaKaRoTo, once the NPDRM algo is fixed, a release will come?
[07:31:14] <KaKaRoTo> heri, another missing bit, but once that’s fixed, yes
[07:31:23] <KaKaRoTo> but I’ll probably be off country for the next 2 weeks
[07:31:30] <KaKaRoTo> so all work will have to be paused :p
[07:31:52] <heri> oh, fair enough. we can all wait 2 weeks hey we have waited months anyways
[07:32:06] <KaKaRoTo> ddoo, that might work.. you could also just install your pkg on 3.55 then upgrade…
[07:32:20] <KaKaRoTo> ddoo, upgrading doesn’t delete any of your packages :p
[07:32:37] <KaKaRoTo> ddoo, issue is, you’re lost if you didn’t do it before upgrading
[07:32:53] <ddoo> but they fail because the npdrm algo is spoted by the checks in 3.56+
[07:33:13] <KaKaRoTo> heri, also note, I “announced” it because I was excited to see it work as expected
[07:33:22] <KaKaRoTo> doesn’t mean it’s ready for release
[07:33:31] <KaKaRoTo> ddoo, exactly
[07:33:36] <heri> yeh thats what we were saying just before you came
[07:33:43] <KaKaRoTo> so you need : 1 – npdrm algo fixed, 2 – a way to install stuff
[07:33:53] <heri> you only announce when you are confident it works
[07:33:58] <KaKaRoTo> 1 has been done by someone else (don’t know if he’ll share it), and 2.. well, I just did it :p
[07:34:37] <KaKaRoTo> heri, well, I was testing on 3.60 and it worked, but yes, I did upgrade to 3.73 to test that it still
works just to make sure I don’t tweet any false hopes
[07:34:46] <middleman> but you cant run what you installed until 1 is fixed correct?
[07:34:59] <KaKaRoTo> middleman, exactly
[07:36:17] <middleman> interesting
[07:36:19] <docpaul> nice, thx KaKaRoTo
[07:36:40] * KaKaRoTo needs to hide now if he wants to get any work done
[07:36:42] <KaKaRoTo> ttyl

UPDATE 1:

It seems as tho developer kakaroto has been flooded with questions regarding his 3.73 jailbreak that he announced late last night. here is a copy and paste from his blog.

Hi all,

I’ve been flooded with questions on twitter and I’ve read many posts on news sites and I’ve seen some stuff being said on IRC and I thought I needed to clarify a few things…

First of all, I didn’t expect to see my tweet front paged on all ps3 hacking news sites.. although I should have expected it.. but anyways, the “jailbreak” is not ready to be used, at all. I only tweeted that because I was excited having it working and I wanted to share my excitement with everyone. But this is a bit equivalent to the day I released that create_cfw.sh script that created the very first CFW/MFW but it still took a couple of months before a real, easy, multiplatform and fully fledged solution was released : PS3MFW.

We are currently at the same state, I have the proof of concept, it works, but a solution that anyone can use where they just click a button and their PS3 gets jailbroken is still far from ready.

I’ve seen people say (and even write it in their front page news) that I’ll release it in two weeks after I come back from vacation. That is not true and I never said that. What I said was that for the next 2 weeks, the project is on hold until I get back.. but when I get back, then I will continue working on it, and it will then take some more time before it’s ready and released.

Some asked if it’s based on what gitbrew was doing/suggesting or if I used someone else’s exploit or work. No, this solution is my own idea and 100% my own implementation. However, the actual solution for the full jailbreak involves some components on which I will not work, and I expect/hope that someone else will provide the solution for that.

Some speculated it might be what I spoke about back in March which I later said I wasn’t pursuing by lack of motivation.. and yes, you are right. The same hack I had in March is still valid today, I told a few people about it (rms, Mathieulh, an0nym0us, and a couple more), but no one was interested in pursuing it further and actually exploiting that flaw (mainly because it requires a huge amount of work to get a proof of concept working). 10 days ago (I started on the 11th), I got bored and decided to start poking at it again, and yesterday (a lot faster than I thought it would take), I got my first pkg installed on 3.73 firmware.

On twitter, I said “do not update if you are on 3.55″, I said that in response to someone who said he would update. Because of that, people speculated that you need to be on 3.55 first, and then install something before doing the upgrade. No, that’s not it, that would be useless. The purpose of my solution is to jailbreak a ps3 that is already on 3.73 firmware and which had never been jailbroken before. I told people not to update because, first of all, it’s not yet ready, and second of all, the 3.55 firmware gives you a lot more possibilities than what can be achieved on 3.73.

So what is this jailbreak? I won’t say because I don’t want Sony to block it in a firmware update (and yes, they potentially could) before it’s even released (and yes, I will release it when it’s ready). But I will explain this to you : in order to run your homebrew apps, you need two things. First, to be able to install them on the ps3, and second to be able to run it once installed. I did only one of these two things.

Some may say it’s not a real jailbreak, but the way I see it, there are three ‘jails’ on the ps3, I broke the first one which prevents you from installing anything, so now you can install your .pkg, great, but it won’t run, that’s the second jail. The third jail is being able to modify the firmware (peek&poke).

The second jail (running apps) is something that can be done, but it’s not my area of expertise (npdrm algo), so I will not be working on that. I am waiting for someone else to achieve it (some have succeeded but do not wish to release it, at least not for now) then I will release.

The third jail (modifying the firmware) is not possible with my method, this means that you will not have a “CFW”, you will run your homebrew applications and games on an official firmware. This also means that without peek&poke support, none of the backup managers will work. So, again, my solution is piracy-free, and as always, I do not plan on working on a way to enable piracy (or even legal backups).

Overall, the purpose will be to allow people who are on 3.73 firmware to enjoy the homebrew games that were released, to play a bit with Eskiss, and to use Showtime for playing their movies. This should be more than enough for everyone.

Finally, I will conclude by replying to another question I received : Do you accept donations? The answer is yes. I do accept donations but I do not seek them out. I will include a donate button to the bottom of this post, so if anyone wishes to donate, they can do so, however, I want to make it clear that whether or not you donate does not and will not affect in any way, the release, or the progress of the work I’m doing. If you donate, you would do it as a sign of appreciation of my efforts, and not in exchange of any favors or anything crazy like that.

That’s about it I think… If you have any more questions, please refrain from asking them, I get enough as it is already.. I also said everything I needed to say and I don’t want to give any more information than that (for now).

UPDATE 2:

A small F.A.Q created by euss.

Q&A
Q: Will I need special hardware?
A: No.
Q: Will homebrew work?
A: With NPDRM fixed, yes. Showtime would certainly be possible.
Q: Will recent games play correct
A: Yes, its 3.7x, sure it plays all 1.00 – 3.7x games.
Q: Does it have Peek& Poke?
A: No.
Q: Do Backup manangers work?
A: No, see previous answer.
Q: Does it gets us keys
A: No.
Q: Does it gets us “CFW”/MFW?
A: No.
Q: Will it allow downgrade?
A: No.
Q: So why are all the newssites hyping this that it does?
A: Because they don’t read wiki’s/blog’s xD Besides, every minor news gets ‘prolly CFW soon!’ tagged by the bad ones.
Q: Is there a release date?
A: No, besides KaKaRoTo not able to work on it for 2 weeks, it also relies on (other people?) fixing NPDRM.

Hopefully that will clear a lot of misunderstandings by people.
