MTextReader is a java app for textfiles that will run on any phone. Works well on the Bold. I mapped the left and right buttons to Q and P respectively.
Wattpad is more Bold native, and allows for downloading wattpad format stuff off the internet.
Mobipocket is another. Mobipocket and eReader both are electronic book ereaders that you usually pay for the books (the readers are both free). I can't comment on shortcovers as I have no experience. I like both Mobi and eReader just to have options for unexpected "down" time. It takes some adjustment getting used to reading from a bb screen (versus an actual book) but I find after about a chapter I'm fine.
I don't know how anyone could stand the idea of reading all those words on a phone screen. I think my eyes would fall out. Have you ever thought of listening to your books on your BB? I found a place called booksfree (Online Book Rental Service, Rent Books or Audio Books on CD at Booksfree - Books Version of Netflix says O Magazine), and no, they are not free, but for $19, or $29, or $35 per month (depending on how many books you want to have checked out at one time) they ship you audio books. It's a huge library, they pay for shipping and I just rip them to my BB and listen. It's great because you can listen to a book while doing things like driving, watching a ball game or kids practice, blah, blah, blah.
I use dailylit.com. Not really an ebook reader but they send chapters to you daily via email. They don't have a wide range of titles but I find it works just as well if you find something you like.
