Collaboration software company Huddle rolled out three cool new tools last week, including a new iPhone app. The free app lets users share documents and whiteboards and hold discussions on their phones. Based on the comments on the Huddle blog, the software seems a bit buggy, but the company is working on the issues.

For desktop users, Huddle's new Microsoft Office plug-in lets users access Huddle files from Word, Excel, and PowerPoint. You also can save and upload desktop documents into your online workspaces.

Meanwhile, Huddle also introduced a new web conferencing feature that lets people set up meetings and share their screens with other workspace members and invited guests, which makes it a handy tool for presentations and demonstrations. Minutes are included in Huddle's monthly packages, which range from a free ad-supported version to a $200 a month enterprise version.
