If you are on a BlackBerry but have trouble installing Opera Mini on your phone or if the browser fails to connect to the internet, here’s a simple workaround.
1. Open http://mini.opera.com/ in your BlackBerry browser (not your desktop web browser) and select the version that mentions "No Signature" in brackets.
You’ll see download links that say Verisign / Thawte / Multiple Certificates - ignore them and download the unsigned version for your language. Here’s a direct link.
2. Next, open this help page in your desktop to determine the APN internet settings for your mobile service provider.
Open BlackBerry Settings -> Options -> Advanced Options -> TCP and type the APN value in the space provided. You may keep the user / password field blank if no value is specified on the Opera help site.
This excellent advice is courtesy Navjot Pawera - Thanks. Opera Mini does seem like a nice alternative to the built-in BlackBerry Internet browser.
