Good.iWare on Thursday released a new version of its PDF viewer app for the iPhone and iPod touch, GoodReader 2.4. Optimized for large PDF or TXT file viewing, the program provides file searching features and enables users to download content from the web simply by entering URLs. Version 2.4 finalizes the PDF Reflow function, which was previously available as a beta, and allows users to extract text from a PDF page for displaying as a TXT file.
