Any Android PDF viewers with user-defined bookmarks?

http://www.mobileread.com – Are there any Android PDF viewers with support for user-defined bookmarks? I mean bookmarks the user can set at arbitrary locations in a PDF document (e.g. for recording the last read page), not the predefined TOC bookmarks that come with the file. EDIT: I'm equally interested in PDF viewers that, although they may not provide bookmarks, keep track of the last read page. (HowTos)
