I use the Cingular 8125 which is the cheaper version of the same phone. I have had this phone for about a year now, but have used scriptures on a PDA for about 2 years. On this phone I have used the following two products:
YanCEyWare - avskip mentioned this one. This is a good reader with plenty of content available on the
LDS site, as well as on the
yanceyware.comsite. There are other locations where you can get content for this, or you can make your own following the instructions provided on the Yanceyware site. This is great software and you can even customize the library following HTML coding instructions provided the Yanceyware site. I have tried this once, did not have the time to really get into it, but was able to download an already created library shell which looks good.
This program is designed to be used with touch screen phones so it works well for the 8125 and 8525. You can, however, customize the buttons to your liking to minimize having to get out the pointer thingy (brainlaps). This is donation-ware so if you find it useful you can donate on the Yanceyware site.
Mobipocket - This is also free and there no donation option that I found. There is lots of available content for this software on the
LDS site, and plenty more on the
mobipocket.comsite. There is a lot more non-LDS content available for this product, but much of it is not free. I recently purchased a package that included thousands of LDS books and non-LDS classics as well as other things. It works great, but after replacing my phone recently I have not added the Mobipocket back on yet. Makes me wonder if I really need it.
This product was designed with Smartphones in mind so you can use the buttons to get around and using the touch screen is not an option sometimes. I prefer the touchscreen so never really got into the button navigation.
There are plenty of options available - you can check out some on the
LDS Church Publications for Handheldssite.
