Hi i was using opera mini before on my sony ericsson phone, and now i wanted to install opera mini in my bb 7130g, is it possible? how?

Should be:
Opera Mini - Download

The 7130e is listed, use that configuration.
I won't promise great browsing on the 7130 though, quite an old device.

thank you again sir, i will try my luck....

sir i connected my usb cable to my desktop computer but i cant find my blackberry phone reflected on my desktop though my pc said that its ready to use.... what do i need to have for me to be able to see my phone registered to my pc? many thanks in advance to you sir....

On the 7130g, there is nothing to see on your BlackBerry, there is no need to see it.

If you are loading Opera Mini via your PC, open Desktop Manager and Application Loader

sir, you mean to say NO need for pc suite? just connect my blackberry to my pc? Where can I find the Desktop Manager sir? sorry because Im not that techy so I dont know where to start, I only wanted to have an Opera mini installed to my bb 7130g...

I downloaded a usb driver, and I dont know if this will work.... Desktop manager is the portion below the screen right? i cant see any icon/s that tells me my phone is connected... after I plugged my phone, there's a pop up message that the device is ready to use then it suddenly disappeared below the screen of my pc (desktop manager)... so i cant find it now in my pc....

You can OTA Opera Mini from their site
