Zoho went live with iZoho, which provides iPhone-optimized access to Zoho’s online office applications. iPhone users who visit www.izoho.com can view Zoho Writer documents, Zoho Sheet spreadsheets, and  Zoho Show presentations – and edit Zoho Writer documents – from the Safari browser. More features are on the way.

iPhone users can also access their Zoho documents at www.zoho.com. However, Zoho optimized the iZoho interface to support mobile access and iPhone’s touch screen, e.g., simpliefied menus and sliding pages.

Zoho anticipates that the iPhone – with its big screen, built in Wi-Fi, good usability, and full-fledged browser – will only improve the use of web applications on mobile devices.

Yet with iZoho, Zoho also recognizes that iPhone users – and mobile phone users in general – face constraints PC users don’t have, such as smaller screens and keypads.
