I'm fairly sure iStorage does this.
Safari will open PDF links.
If you are browsing the web using Safari and find a pdf file that you want to download, all you have to do is modify the address from http:// to rhttp:// and it automatically opens up that address in the ReaddleDocs web browser.
ReaddleDocs is superior to iStorage when it comes to downloading stuff. If you are browsing the web using Safari and find a pdf file that you want to download, all you have to do is modify the address from http:// to rhttp:// and it automatically opens up that address in the ReaddleDocs web browser.
