Gold master already headed to developers
In an unexpected turn, Apple has announced that it is renaming the iPhone OS. It will now simply be called iOS, reflecting its use on devices like the iPad. As previously revealed, the iOS 4 firmware brings several important changes including multitasking, app folders, a universal inbox and e-mail threading. Newly disclosed though is integration with the iPhone 4 retina display, and updated Camera and Photos apps.
As rumored, Bing has been added as a web search option alongside Google and Yahoo. The firmware's launch should also mark the launch of iBooks for the iPhone, which will be feature-identical to the iPad edition, with notes, bookmarks and PDF support, as well as wireless sync with other Apple handhelds, and the ability to download previously-bought e-books on a second device at no extra charge.
Developers will have access to the gold master candidate of iOS 4 later today. The public release is due on June 21st, and will be free for all compatible handhelds, which excludes only the original iPhone and first-gen iPod touch. In the past, Touch owners had to pay an extra fee to upgrade.
