Bough a 2690 yesterday, It has a Built-in Opera Mini 4.1.x. Is there any way to upgrade it to Opera mini 5.1. I hate this version. 5.1 is much better
The inbuilt opera is firmware embedded and cannot be updated, however you are able to install opera mini 5.1 even withou uninstalling the old one. You will however have two instances of Opera Mini in your phone.
You can get the latest version of Opera Mini for your phone here
To Install through your PC
It would require you to use a USB connector (CA-101) or a microSD card reader to transfer it.
To Install directly on your phone
Go to m.opera.com using your phone's web browser.
