Alternative to Nook on phone (for sideloaded content)
First off, hi everyone. Owned my Nook since last Christmas, but first time posting.
I was a little bummed about the sideloading situation on the Nook's phone apps, but the good news (if you use an iPhone) is that Stanza is a fantastic alternative. Load Stanza onto your phone (it's free). Then in iTunes, choose your phone, click on the Apps tab, then scroll to the bottom of that screen. You should see where you can load documents to Stanza there.
While I do prefer reading on the Nook, there are times when either all I have with my is my phone, or light levels are too low and I don't have a lamp available to read by with my Nook. For sideloaded content, Stanza for iPhone (hopefully there are equally good apps for other phone OSes) is great.
