Look here:
http://yuetblog.blogspot.com/2006_08...g_archive.html and then search down for "YuetReader v1.0". This blog describes a java reader for some Motorola phones. At the end of the entry there are three download locations where you can get the 35K jar file. To use the reader you must package it with your text file(s) in a zip file, then install it to your phone via USB. Instructions for this are included in the article. I have not tried it.
