Is Steve Jobs Using A Jailbroken iPhone ?

9 to 5 Mac has an article today about a Mac user who emailed Steve Jobs and received an answer back from him, showing that Steve-o was still using an iPhone running OS 3.1.2.

Why would Steve Jobs use an iPhone with 3.1.2? Well, my guess is that he simply has a jailbroken iPhone and he doesn’t want to update to 3.1.3 because he knows it brings nothing more than 3.1.2, except the few usual “bug fixes”.

Additionally, I believe Steve doesn’t want to lose the ability to unlock his iPhone so he can use it with T-Mobile.

Any other reason why you think Steve Jobs would still be using an iPhone on 3.1.2?
