Desde el lanzamiento de iTunes 9 y el sistema operativo 3.1 para iPhone de ayer los desarrolladores estuvieron ocupados analizando el software para encontrar posibles cambios.

Así están las cosas por lo pronto...

- MuscleNerd confirmó que es seguro hacer el update a iTunes 9 para aquellos que ya hicieron el jailbroke y el unlocked.

- saurik notó que Apple bloqueo el downgrade a la versión 3.0 para usuarios de iPhone 3GS. Esto quiere decir que ya no pude firmar hashes para los usuarios. Los usuarios que hayan salvador su información ECID SHSH tendrán que esperar a que alguien desarrolle algo para cha información. En un futuro postearemos más información. Mientras tanto podría interesarles chequear estos (Windows, Mac) tutoriales.

- chronicdev confirmo que el iPhone 3.1GM todavía es vulnerable

-el nuevo firmware incluye una actualización de baseband que hace perder el unlock a menos que tengan un iPhone 2G o un iPhone 3G con el bootloader 5.8 . Si tienen el bootloader 5.8 estén al tanto que no hay herramientas disponibles para el downgrade de baseband todavía.

- No deberían actualizar a la versión 3.1 si tienen el teléfono jailbroken o quieran jailbreakearlo en el futuro cercano. ¡Esperen!

i have a J/Unlocked iPhone 3gs with3.01. i downloaded iTune 9 and it is working fine: QUESTION: can I download and install the " iPhone Configuration Utility Version 2.1" or will it cause problems with my Jailbreak and Unlocked iPhone.

danikno1 - September 13, 2009 at 1:25pm

I have a 3gs on 3.0 FW and I successfully JB'd & unlocked. After JB'g, I wasn't aware I needed to reset the phone before adding other cydia applications. My phone started crashing, but I was able to get it to come back up once. Since then I can't get it to boot up properly. It just keeps displaying the apple logo and the screen goes black. I've tried to run redsnow, but keep ending with an error message toward the end about an incorrect block count for file data_a rk.plist (it should be 1 insteas of 0) Invalid index key (4, 1) ** Rebuilding Catalog B-tree. disk0s2s1: alignment error. ** The volume Data could not be repaired . Mounting rootfs as read-write... Mounting devfs... Mounting disk0s2s1... ERROR! It stops at this point and staying at the program screen and does nothing further. Please Help. I have not updated through I tunes because I don't want to increase the baseband. My phone is not operable. Please assist???

dt - September 13, 2009 at 6:05am

You bought the phone. You knew they would be upgrading it. man up or sell the phone.

Lez - September 12, 2009 at 3:05am

zé - September 11, 2009 at 5:04am

I have a 3g.

p..e - September 11, 2009 at 5:05am

If you don't have the original sim card the iphone will not be recognised by itunes. It seems you are waiting on hacktivation, which will come on stream IF and WHEN DevTeam find the necessary exploits for the jailbreak and unlock. If you don't have the original simcard your goosed, you wont even be able to use it as an ipod. Lesson learned here folks, always better to wait until your told to update like with all updates to iTunes and the iPhone

p..e - September 11, 2009 at 5:10am

I presumed you were 3GS, you have a much better chance of getting your jailbreak back but your bootloader has been updated so there is nowhere to go for now. Wait on news from the Dev's, they will either exploit the new bootloader or enable some way of downgrading the bootloader. Either way you have nowhere to go for now but you must have faith!

zé - September 11, 2009 at 5:13am

Thanks for the support.Im on an Iphone 3 G.

Zeljko - September 11, 2009 at 7:51pm

I have name 4 this kind of People TRIGGER FINGER

marbie - September 11, 2009 at 3:46am

whew, i just hope iphonedev team will finally solve the problem, anyway, i am planning to buy Iphone 3G , probably it will be an at&t prepaid kit, and will jailbreak/unlock it. Does iphone 3g also affected by the recent problem faced by iphone 3gs users?

Liz - September 11, 2009 at 3:43am

I want a straight answer. Here's my dillemma. I am worried that even if I will be using Itunes 8.2 version and OS 3.0 and the appropriate redsnow program and ipsw, the Iphone 3Gsthat I am planning to buy by October will not be jailbreakable/unlockable? Am I getting the right infos? Pls someone help me.

p..e - September 11, 2009 at 3:57am

There is no straight answer, maybe things will become clearer by the time October comes. If you can, buy the phone today as it will not be factory 3.1 and you will have a better chance of a jailbreak and unlock.

Zeljko - September 11, 2009 at 5:59am

That was a good answer.

jorgealina - September 12, 2009 at 12:52am

you can jailbreak and unlock it

liquidator - September 13, 2009 at 11:28am

so , pe, your'e saying that I can buy an 3gs today (9-13-09) and still be able to jailbreak and unlock without a problem (hopefully)?

Allen - September 11, 2009 at 12:35am

Unfortunately because now that iTunes checks in with Apple everytime a restore is performed, the tutorial to obtain the iBEC file is now useless :-(. I have tried on several machines with several versions of iTunes, and no success. I am still on OS 3.0.1 and have not yet upgraded to 3.1. If anyone knows how to get the iBEC still, I'd love to know! Thanks :-)

sss - September 11, 2009 at 1:14am

If any one not care about wheter your phone be jailbreak/unlock. easiest way to upgrade your 3GS using Itune 8 restore your firmware 3.0.1 (do not jailbreak). then upgrade your your itune 9. then last step just update your iphone firmware to 3.1. I have done this on my and it work just fine.

Allen - September 11, 2009 at 1:21am

The problem is that for me, iTunes 8 (even when running on Leopard 10.5) also checks Apple's server to make sure that it's the latest version of the iPhone OS that wants to be restored. For instance, if I disconnect from internet and try to restore, it won't restore. It gives me an error until I reconnect to the web. Does that not happen to you?

p..e - September 11, 2009 at 6:10am

This is precisely why everybody was told 100's of times to get the files months ago, if you didn't then you have no one else to blame but yourself. Sit tight, with a bit of luck the devs will figure it out. What is the big panic to go to 3.1 people, it's features are not worth jeopardizing your phone functioning as it has done for months now. SIT TIGHT

Allen - September 11, 2009 at 11:46am

Noone is blaming anyone (at least I'm not). It's cool, these guys ALWAYS find a way, which is so incredible to me. I think I'm still having a hard time understanding exactly what these 2 files do, or are for. There are so many tutorials on getting them, but I don't understand how they'll help in a situation like this. I think what someone should figure out is how to route the iTunes s/w verification service to a DB which Saurik or someone else can create. That way, he can tell the service "ok, 3.0.1 is the latest s/w" and that's it, no problems. I know it's not as simple as that, but it's an idea.

peter - September 10, 2009 at 10:28pm

ok i just update my iphone 3g with the 3.0.1 firmware from apple. I know i shouldnt do this.Now it means that i cannot jailbreack my iphone anymore and i need to wait for a new release???? thanks

Jay - September 10, 2009 at 12:42pm

Upgraded to iTunes 9.... Apparently you can not organize your Apps if its Jailbroken?

Erik - September 10, 2009 at 1:43pm

To reorganize your apps from iTunes you'll need the 3.1 on the iPhone as well as iTunes 9..

Elise - September 10, 2009 at 11:33am

Wait, wait,wait... If I purchase an Iphone now, I will not be able to jailbreak/unlock it even in 3.0? I was about to buy but then I was alarmed lately by numerous complains. If history would be the indication, iphone dev have always made workaround. but this time, aee we saying we are confident we can still jailbreak iphone 3gs?

berkekibris - September 10, 2009 at 12:17pm

We are confident in the dev team for a jailbreak because: 1. IN DEV TEAM WE MUST BELIEVE!!! 2. They already confirmed the vulnerability, now they just need to get it signed.

elise - September 10, 2009 at 8:18pm

Thanks, berkekibris, you certainly gave me reason to hope..I am going to buy an iphone and jailbreak it!

black - September 10, 2009 at 11:07am

i have an iphone 3G running 3.0, is it safe to update to 3.1 and still do a jailbreak and unlock?

Fadil - September 10, 2009 at 11:54am

NO, NO, NO....

RMJEEVES - September 10, 2009 at 6:44pm

Not sure why people keep asking the same question when the asnwer is all over the internet......WAIT!!!

Gustav - September 10, 2009 at 11:04am

I have an iPhone 2G with 3.0. Is it safe to update to 3.1? I don't need jailbreak. Will be still unlocked?

berkekibris - September 10, 2009 at 12:15pm

NO NO NO!!!!! Read the last part of the topic!!! It is NOT safe yet!

vanimox - September 10, 2009 at 9:24pm

YES! The 2G is OK to upgrade and you'll still have the unlock, its only the 3G & 3GS that have to wait, once the 2G is unlocked it can't be undone, but you might want to wait because there might be some unoffical activation issues...

Jason - September 10, 2009 at 11:00am

That is correct if you update to iTunes 9 it will not allow you to downgrade your firmware manually. I would just wait for dev team to release update. Im sure it will be up within a few days. They verified the jailbreak vulnerability is there, they just need to figure out the baseband issues.

Allen - September 11, 2009 at 12:36am

Any version of iTunes (including) 8.2 now "phones home" to ensure the s/w we are installing is the latest. Apple updated that as well. I have tried with 8.1.1 through iTunes 9 to restore to 3.0.1 (from 3.0.1) and it would not let me. Kept telling me something to effect of "there is a newer package available".

Jay - September 10, 2009 at 10:37am

So those that mean that I can't do a restore of my 3GS that is still on 3.0( but giving me issues), to 3.0? If so then that really sucks ass. I am seriously contemplating updating to 3.1 but don't think I can bare with loosing my apps.

DistortedLoop - September 10, 2009 at 10:42am

Yes, that's exactly what it means *IF* you have a 3GS. Apple will not sign the firmware for anything other than 3.1 now. Signing is required to successfully install the firmware to a point that you can then jailbreak it. According to BiG Boss' Web site, 3G and earlier are not impacted.

IJunkie - September 10, 2009 at 2:57pm

Wouldn't this be a lateral type thing. It truely is not a downgrade, just keeping the same firmware. So is using Itunes 8 and restoring to the same firmware 3.0 that is on your 3gs also considered a downgrade? Does this mean anything other than using firmware 3.1 will be considered a downgrade? Thanks

TheDon - September 11, 2009 at 7:32pm

Correct. Even installing the same firmware is considered a downgrade. Just tried jailbreaking my 3gs and it will not sign the firmware.
