In a new record time, Apple on Friday released iPhone Software Update 3.0.1, patching a SMS vulnerability demonstrated on Thursday.

The flaw, disclosed at the Black Hat security conference, allowed an iPhone to be taken over remotely through the CoreTelephony framework. The vulnerability created a memory corruption issue in the decoding of SMS messages.

The new update, with the patch being the only new item to be offered, still manages to clock on at a hefty 280mb.

The vulnerability, which takes advantage of a commonly used protocol, has remained unpatched by other manufacturers.
