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