Steve Jobs Still Using iPhone OS 3.1.2; Surely Not Jailbroken?

Since the iPhone OS 3.1.3 update came out, the word has spread far and wide among jailbreakers: don't upgrade! There's no reason to do so, as no new features were added, and a "safe" effective jailbreak couldn't be guaranteed.

It is interesting, therefore, to see that Steve Jobs hasn't upgraded his iPhone to 3.1.3, either. 9to5Mac, while confirming the validity of an email from Jobs to a reader, took at detailed looked at the email header. What they saw was (above) that in the X-Mailer section it said: iPhone Mail (7D11) which means he's on 3.1.2.



There could be many reasons that Jobs is on 3.1.2. It's quite possible that Jobs simply can't be bothered with syncing his own device and relies on his admin to do it. Surely it's not because he's using any of the numerous useful apps available only on jailbroken devices, right (such as Intelliscreen, shown above, which shows information on your lock screen)?

In the past Apple has said that jailbreaking devices is illegal. In 2009, as part of the 2009 DMCA triennial rulemaking process, Apple filed comments (.PDF) with the U.S. Copyright Office as part of the 2009 DMCA triennial rulemaking, claiming that jailbreaking an iPhone constitutes copyright infringement and a DMCA violation.
