ebook reader software

I work usually with heavy PDF files that are generated by scanned images (like old books etc.). I have used several mobile readers and I would suggest the following for each mobile OS in the order presented. I didn't find any adequate PDF reader for J2ME phones... However, for ePub format Albite Reader is great!

1. iphone: 
1. iBooks (PDF, epub, apple) 
2. Stanza (PDF, epub) 
3. Good Reader (PDF, Word, Excel, etc.)
2. android: 
1. Aldiko (epub, PDF)
2. Adobe reader (PDF)
3. FBReader
3. java phones: 
1. Albite Reader (for epub, txt, xhtml formats)
