I have the olive tree on my Ipaq. Only downside is that the bible versions are limited and they mostly only offer the versions that you must pay for licensing. It's not my first choice but it works fine on my Ipaq running under Windows so I use it for now. You may need more memory.
Basic Bible text only, no accents, definitions, or study aids. Entire Bible: 1.4- 1.6 mb

BibleReader, to read the text databases
PalmOS 231k
Pocket PC (Windows CE) 300k
Just for basic NT text and the reader it will install around 700k so you may want to free up more memory or install on a flash card/extended memory if you can get it.
Also, there is
PalmBible+ that you can grab for free. He has public as well as commercial translations and it should install with in the amount of memory you are using. I have not used it (palm only) so if you try it let us know what you think of it.
I think the
Qtopia Sword Reader is the best with its 250 books you can view/refrence with it but I cant run it on my Ipaq with Windows. I run the PC version of this and love it but maybe someday I'll get it going on my mobil.
