What I found searching the Opera Forums:
"Opera Mini will not work on a Treo 650/680 unless you change the preferences in IBM Java as follows:
To get to the IBM java prefs, you need to go to the prefs icon on your Palm desktop, open it, and scroll way down until you find IBM Java.
Clicking on that allows access to making the following changes.
Double Buffering: on
High-res coords: on
Memory Max: 1Mb
Stack Size: 32Kb (use the slider to fill the bar all the way to the maximum 32Kb)
The problem is that the application hangs up on a prompt to sign the user agreement if the settings are not changed in IBM Java. You cannot use OM until you complete that task."
Did this and it worked...hope it helps someone else!
