Minor release targets bugfixes
Distributing through iTunes, Apple has released a new iPhone firmware update, v3.1.2. The code adds no new features, and instead fixes bugs, such as one preventing sleeping iPhones from waking. Also targeted are crashes during video streaming, and a bug which interrupts cellular connections until a phone is rebooted.
A similar firmware update is available for the iPod touch. Download sizes may vary, but should begin at a minimum of 200MB. American iPhone owners are being given a parallel AT&T carrier update, v5.6; it is unknown what changes the code makes.
