Apple Releases iOS 4.0.2 [Don't Update] [3x]

Posted August 11, 2010 at 3:29pm by iClarified
Apple has released iOS 4.0.2 for the iPhone. Do not update your device until more details about the firmware are discovered.

It is VERY important that you have your SHSH blobs for 4.0 or 4.0.1 saved. Apple will stop signing 4.0.1 in just a few minutes/hours.

Follow one of these tutorials ASAP:
- Windows
- Mac


It's thought that the 4.0.2 update will patch the PDF vulnerability that comex used to perform his jailbreak.

Update:
Planetbeing tweets that Apple hasn't bothered to patch the exploit for the first generation iPhone. Are you serious, Apple's not going to patch the Safari remote execution on the first gen iPhone???!

Update 2:
Apple has posted a support document outlining the security issue that has been fixed.

A stack buffer overflow exists in FreeType's handling of CFF opcodes. Viewing a PDF document with maliciously crafted embedded fonts may allow arbitrary code execution. This issue is addressed through improved bounds checking.


Update 3:
MuscleNerd notes that the baseband hasn't been updated in 4.0.2. iPhone 4 baseband isn't updated in 4.0.2, but ultrasn0w requires JB. 4.0.1 SHSH blobs will protect you from "oops" update

I jailbroke my iPhone 3G with jailbreakme.com first with ios 4 and then 3.1.3 and noticed that loses wifi connectivity with my modem. I have to switch thevphone several times before the connection re-establishes. It becomes frustrating after sometime. Can anyone tell me why this happens?? I restored back and without the jailbreak I don't lose connectivity.

My iPhone is crashing, etc. I am wanting to do a software restore and then re-jailbreak. SHSH Blobs are saved at 4.0.0. I have downloaded the 4.0.0 update and click option-update or option-restore and chose the downloaded 4.0.0 update. It looks like it is working until it contacts Apple. Then it says something like the device is not eligible for the update. Is there still a way to do this, or am I going to have to restore to 4.0.2 and wait for another jailbreak?

Hi, if you have the 4.0 or 4.0.1 ipsw saved on your computer you could allways hold the shift-button and press the update button. That should help you out ;) just Google the 4.0.1 ipsw, you find it 100%

So its not possible to download an older firmware (ofcours newer than whats in the iphone) and just upgrade the iphone with the file by pressing shift+click on the update button? How did they managed to disable that feature?

Hey guys i just noticed that you can still go back to 4.0.1 just download the 4.0.1 firmware from the net and then go to itunes and press shift key and update at the same time and that will do it ....it works tested by me just now ...this only may last for today or tomorrow so do it fast..enjoy.

well if your ios 4.0 was jailbroken, surely you went onto cydia, after all that is why we jailbreak anyways (unless you only jailbreak for installous), and when cydia starts the 1st time, it asks if you want to make life easier, a simple yes and 1 min wait is all it takes!!!

The Apple Empire will tumble from here on. Their stock price has topped off. The downward spiral has begun. This is what happened to Google last year. Bye Apple!

IOS4 isn't supported on the iphone 2G. So, natrually apple won't patch it.

I always wonder why Apple needs to release a full firmware "ISO" for updating just some bytes of code. Thank of god that doesn't happen with Windows, imagine download and install 5GB every month? they need ASAP implement a iPhone updater to download some bytes and update.

But that's just it, it's not 5GB, and it's not every month. It's like once every 3 months or so, and usually with multiple changes as opposed to a single patch. Note that OS X does have single patch updates. My guess is that it makes the iPhone far more efficient to simply replace the firmware in its entirety than develop the architecture on it for patches.

It's every "3 months or so" for this same reason, if they implement the updater, the updates will be every week.

NeHoMar, I say "No Thanks" to having anything of mine automatically updated. Especially if you're Jailbroken.

thats not true. My N900 can update individual packages. I never have to download the whole fw. Sometimes the update is 30 megs, sometimes its 100 megs. Still they update it every 3 months.
