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.

Instead of saying 'fixes PDF vulnerability', it should have read 'This update fixes Steve Jobs fragile ego that was hurt by an exploit that led to Jailbreakme'. What a bunch of cheapskates.
