Quickoffice lets you edit or create Microsoft Word and Excel documents on the iPhone. To edit a document, transfer it to your device via e-mail or a wireless network. You can then open it from within the app and add, delete, and format content. I was a little disappointed that the app does not support more document formats such as WordPerfect, Google docs, etc. However, it’s great to be able to work with Word and Excel. In one stroke, this app has turned the iPhone into a serious contender for the business market.
