ZappTek has announced the release of iPDA 4.1, a software application that enables your iPod to act as "a replacement PDA." A free update for registered users of version 4, iPDA costs $19.95.
iPDA lets you copy Microsoft Word, PDF, Apple Pages, RTF or text documents to the iPod. The software also supports information transfer from Gmail, Apple Mail, Address Book and iCal.
Version 4.1 adds support from Entourage 2008, the latest major revision of Microsoft's e-mail and personal information management software. Other new features include the ability to display Gmail messages in their own Gmail folder on the iPod, improved RSS feed processing and a fix to the News downloading option to account for U.S. election news.
iPDA requires Mac OS X v10.4 or later and an iPod.
