Looks like operamini silently updated to version 4.2.14320. Though there are no new features but this could mean many bugs have been fixed.
Though my phone comes with default browser in it, it’s not as fast as Opera Mini. Apart from loading sites faster it also loads website content correctly than the default browser on my Sony ericsson z550i.
What concerns me about using Opera Mini is that it uses proxy servers to send data, so not quite secured.
