ReaddleDocs, an awesome and highly useful file manager app for the iPhone, has gone free on the App Store.
ReaddleDocs is all-in-one document reader for iPhone and iPod Touch.
It can catch documents from any source you can imagine: PC or Mac computers, web sites, email attachments, iDisk, Dropbox and other online file storages and even iPhones. All files are saved to your iPhone or iPod Touch locally so you can enjoy reading them anywhere!
Besides being able to unzip files and merge several into archive, the app also features a more than capable PDF viewer that supports text reflow, highlighting, full text search and more. Be sure to snag this while it’s free, which probably won’t last more than a day or two.
