I had to restore my iPhone because my home button broke. And when it restored it it went to 3.1.3. I have 3.0, 3.1 and 3.1.2 SHSH on file with cydia. I followed the instructions at iclarified to change the hosts file. But after getting the 1015 error twice when restoring to 3.1.2 then running redsnow, it jailbroke my phone but in had no signal/activation from att. I did it again with blackra1n and same thing. Is there a fix for this?
 
The new bootrom 3gs is the ONLY iPhone to have a "signiture" within the firmware. For those who don't realize, FIRMWARE is different from OS version. FIRMWARE is the bootrom, OS version is 3.0, 3.1, 3.1.2, 3.1.3, 3.2, and so on.

This is NOT true. Everything in this paragraph is wrong.

1) All 3GS phones, regardless of bootrom, must have their firmware signed by Apple when restoring or upgrading. The only difference between the old and new bootrom 3GS is that the new bootrom does not contain the 24Kpwn exploit which is currently the only publicly-released way to create an untethered jailbreak.

2) Your terminology is all wrong. When discussing the iPhone and iPhone jailbreaking, firmware does, in fact, refer to iPhone OS version. While it is true that the bootrom is technically 'firmware,' it is always called the "bootrom" and never called "Firmware" to differentiate it from the OS version. Likewise, the "modem firmware" stored on the SGold chip is called "baseband" to differentiate it from the iPhone's other firmware. To sum it up for you:

Firmware = iPhone OS version (3.0, 3.0.1, 3.1, 3.1.2, or 3.1.3)
Bootrom = iBoot version (359.3 or 359.3.2)
Baseband = Modem Firmware (04.26.08, 05.11.07, or 05.12.01)

There may NEVER be a jailbreak for the new boot rom 3gs for 3.1.3. ...It was stated everywhere that once upgraded to 3.1.3 you will NEVER be able to downgrade or jailbreak. :apple:

This is also false. There are now two known exploits for 3.1.3 which can be used to create an untethered jailbreak for both old and new bootrom devices. One of these, "Spirit," is already being worked into an end-user jailbreak utility by a combined effort of the Dev Team, ChronicDev Team, and its discoverer Comex. This tool will work for any 3GS device on 3.1.3 and even on the iPad running 3.2.

No offence but this thread is quite useless and is a repeat of every noob's question. Sorry, but we are all laughing at you.

No, we are all laughing at you and your comically uninformed rant against "noobs" who don't know what they're talking about. Those who live in glass houses, as they say...
 
Is there anyway to unlock an iPhone 3G on the new bootrom/baseband? My phone is currently jailbroken atm and was wondering if there is a way to downgrade back to 3.1.2.

You can downgrade to 3.1.2, but it won't allow you to unlock. The baseband (modem firmware) cannot be downgraded, and the new baseband cannot yet be unlocked. A way to crash the new baseband has been discovered, and it sounds like it may be exploitable, but nobody is currently working on an unlock for 3.1.3; most expect that those who know the exploit will wait until the release of 4.0 before creating a new unlock, since 3.1.3 is such a minor upgrade and exploitable weaknesses in the baseband are hard to come by.

I'm having troubles downgrading to 3.1.2. I have my SHSH on file with cydia. I did the restore twice and got the 1015 error then ran redsnow but after reboot it was jailbroken but it would connect to att. Is there a fix for this?
 
So can someone give me a link to jailbreak my 3G iPhone?

its running on version 3.1.3(7E18)

I'm crap at technology and just want to change my text tones,new mail tone and I guess tethering to a laptop via wifi would be good.

Are there any commercial sites that can do it reliably, I dont mind paying for this service..

Jailbreak vs Unlock

Excuse my ignorance but I am new on this. I am a formal AT&T customer using an iPhone (3.1.3 7E18) obviously with the new bootrom. I am in shock wondering that I can not transfer files and documents to my iPhone in a "human" way. Can I jailbreak it without necessary unlock it in order to transfer files and install any other app beside AppStore?
 
Now we know 4.0 won't be available for iPad until much later in the year, do you think comex/dev team will press ahead with the jailbreak and release asap? It's my preferred option, had to restore my phone due to wifi issues (tried resetting network settings to no avail) and bam, I was on 3.1.3. And my shsh was for 3.1.3, not 3.1.2. Just want backgrounder back :(

You are right to some extent but i cannot loose hope. i bought just a week before and now stuck with this firmware 3.1.3.okay if dev team release their next exploit after the next iphone comes then would i be able to use that or not or my $700 are just wasted please tell me?
:confused::confused:

$700 !!!! thats the price of an officially unlocked iphone 3gs !!! i got mine with the new bootrom and i did update to the new os from apple never jailbreaked and now i can use any carrier !!! if you paid that amount of dollars you should have an unlocked iphone 2 you should get the new version of the os with no limits ! listen now you have everything official you can take it warranty
 
if your with AT&T and not planing to use another carrier there is no reason too unlock just jb! ;)

I dont want to unlock it to use another carrier. I just want to jailbreak it in order to transfer not media files (pdf, doc, etc) to my phone. Itunes doesnt let me do that. Ive found some 3rd party softwares, but all require to jailbreak the phone first.

Why not use something like FileMagnet?
 
you can visit apple support in your country (here it is called trade line stores), they can unlock it but it will cost you !!!

In the USA, even the original iPhone is not been unlocked by AT&T, their official answer is that they are the only carrier for the iPhone so they don't have to unlock it.
I'm not happy nor agreeing with them, but that was their official answer.

Unlocking is one thing.

Jailbraking is still attractive, even when OS 4.0 will be released:
- Mini vMac
- NES emulation
- Quick changing settings
- etc
