Opera Mini 4.1 for Palm OS.

After you get the gmail app running on your centro, the next thing to get it on your centro would be opera mini 4.1.

Opera mini is very good for rendering complicated website, so it is good to have it on our centro in case the Blazer cannot work for some web pages nicely.

I assume you have installed the IBM JVM in the gmail install guide, so download the opera mini from the following link:

The opera mini will work:)
