Docs is a multi format document reader. Supports PDF, word, excel, powerpoint, iPod videos, and more.

Put files on your device using SSH in folders or however you want. I use /var/docs and make folders in there. Then just scp the files over, or use something like total commander.

As of v2.3, iPHone tilting is supported to view your doc in landscape mode.

As of Docs v2.2, it supports iPod video support so you can watch movies without using iTunes to sync them by sending them via SSH or iPhonebrowser! Thanks to Optimo for AVPlayer source.
