PDF Reader? also Voice Recorder w/out Needing Paypal

My search really started when I saw that there was an eReader app for the iPhone, so I thought I would try to find one for my instinct if one existed instead of spending $150 to $500+ for an eReader. All the books I have so far are all PDF files, so if anyone knows anyway of getting an app for PDF files for my instinct I'd really appreciate it.

I found the site, instinct-software.com and a voice recorder, but the thing is they use paypal, and I don't have an account, and I heard using it sucks, if anyone knows how I can get a voice recorder app without needing paypal, or even better free, I'd appreciate that too.
