Earlier this month, a screenshot highlighting the iPhone's ability with iOS 4 to open attachments in external applications hinted at the possibility of a release of an iPhone version of Apple's iWork productivity suite. The screenshot was quickly replaced with one mentioning iBooks instead of Keynote, although many continued to wonder whether it was a marketing mistake or a product development revelation.

A new discovery on Apple's site again points to the possibility of iWork for iPhone. The mention comes on a number of Apple's international online stores, including sites in Canada, the UK, and Australia. When ordering unlocked iPhones through Apple's online stores in these countries, customers are presented with the option of adding AppleCare to their orders. Clicking the "Learn more" link for AppleCare on the ordering page reveals additional information on the program, with a section devoted to software support specifically mentioning "Using iWork for iPhone and other Apple-branded iPhone apps" as a topic for which users can receive assistance.
A release of iWork for iPhone would not be a tremendous surprise given that Apple has already created iPad versions of Keynote, Pages and Numbers, although the iPhone's smaller screen size would undoubtedly introduce additional challenges for content creation and editing.
