We will test shortly but this is a very serious flaw:
Security experts Bernd Marienfeldt and Jim Herbeck discovered something really interesting when they hooked up a non-jailbroken, fully up-to-date iPhone 3GS to a PC running Lucid Lynx …
I uncovered a data protection vulnerability [9], which I could reproduce on 3 other non jail broken 3GS iPhones (MC 131B, MC132B) with different iPhone OS versions installed (3.1.3-7E18 modem firmware 05.12.01 and version 3.1.2 -7D11, modem 05.11.07) , all PIN code protected which means the vulnerability bypasses authentication for various data where people most likely rely on data protection through encryption and do not expect that authentication is not in place.
