Is it possible to use an iPhone 3GS on ATT and not have to have the data plan is there a way around it?

Why doesn't apple want to comex jailbreak to be used?

It's not actually that. The jailbreak that we know uses a known PDF exploit to be run. By that, I you do not install "PDF Patcher 2" from Cydia, any website that exploits that PDF bug will have full access to your device (hopefully you will not encounter a malicious site). Apple simply patched that bug in order to prevent your device being controlled by other users. Unfortunately, that patch disables the jailbreak, so it's up to you to update your firmware. I personally do not see any reasons for updating my device, I jailbroke it using JailbreakMe and then installed PDF Patcher 2 from Cydia, so I'm protected. Let's say it this way... if you do NOT jailbreak your device (lots of users do not jailbreak theirs) and you open a malicious site, they will be infected. Apple is avoiding that possibility. I don't think it's a direct attack to jailbreakers.

Shit! My iPad is being shipped by Apple... Do you think it will come with 4.3.4??

PReaper - July 15, 2011 at 7:46pm

Probably not.. It was most likely already packed and sealed before the update.. But I could be wrong :/

rick - July 15, 2011 at 8:15pm

it'll probably have 4.3, you'd be screwed either way.

If it has 4.3.3 on it then just use iFaith to obtain that SHSH blob in case a restore is needed. https://iClarified.com/15394 If it's below 4.3.3 then you're probably put of luck.

ifaith does not work with ipad 2.

How can iOS be vulnerable to the SAME PDF hole?? Wasn't that patched already? Guess I am missing something which no doubt the tech irobot dudes will inform me...

Shameer - July 15, 2011 at 6:44pm

It is very similar but not excact plus apple cant not allow PDFs

Frank - July 15, 2011 at 7:54pm

If you mean that iphoes don't allow PDF files, then you are wrong because they do.

Nobo1 - July 15, 2011 at 8:18pm

Darn PDF :/

Shameer - July 15, 2011 at 9:22pm
