I use opera mini on the Nokia; sometimes the app doesn't open anymore but keeps telling me there's an error and nothing could be found. Last time it happened it just came back on after a day or two; now, a few weeks later, same has happened again - no more opera. The site I download it from recognises my phone and links me to the version I need, so nothing wrong there. Downloading it again doesn't help, I'm just waiting if it comes back again, just like it did before. But what might be wrong with it anyway?
