At 6PM GMT Apple released its anticpated iOS4 software. This software apples to the iPhones and iTouch and in the not to distant future the iPad.
Apple have not really said to much about its Security updates, and they dont seem to be that easy to find. However if your interested here is the link to check out the 64 updates covered under iOS4.
As you can see there is alot of information about fixed vulnerabilities, but not what I was expecting an hoping for. I was looking forward to information on general security improvements, encryption, configuration and enterprise level stuff, not just a list of fixed vulns. Time for a good read through this, and further investigation for the corporate use case.
