I use Opera Mini for websites that don't display well in Blazer. You can find it here: www.operamini.com

You will also need the Java Virtual Machine (JVM) which you can find here:
IBM WebSphere Micro Environment Java Virtual Machine 5.7.2 (for Palm OS) - mytreo.net/downloads

After you download and unzip the JVM, you will need to install the following 3 PRC files that are in the ARM4T folder:
J9JavaVMMidp20.prc
j9pref.prc
JavaVMCheck_enUS.prc

After the install, there will be some extra settings for the JVM in the Palm preferences app. For an idea of how to set them properly, see: How to make Opera work really well on 755p? - Treo Forum - Treonauts

Opera Mini has a couple of quirks (at least on my 755p) -- when it asks permission to connect to the internet (with the standard palm dialog) it is really tiny and up in the corner. I just press the select center button and it connects, but the connecting dialog is off the bottom of the screen. After it connects, it all seems to work OK though.
