Cre.ations.net's Nate True wrote a blog post describing what he found inside the iPhone firmware 1.1.3 update. Whilst digging around in the iPhone's firmware innards, he found that Apple has made some startling changes to the iPhone's OS, including:
- The SpringBoard doesn't have to be modified to show custom Applications installed on the iPhone
- Applications no longer run as root, instead they run as 'mobile'
- Preferences are no longer stored in /var/root
