Opera has announced that its Opera Mini 4.2 for Android software has just moved from beta to final release status. Among the improvements in this version is the ability to access the phone’s memory card for uploading / downloading files, support for video playback, double tapping to zoom in or out of a webpage, use of inline URL entry instead of native textbox and more.

Opera has also quashed some bugs in this final version, including one that displayed the characters of your password when you typed it in, and introduced other minor improvements such as a more responsive trackball and a slightly larger font size on most pages to improve readability. If you happen to own a T-Mobile G1 and wish to try an alternative to the phone’s built-in browser based on WebKit, you can get this new Opera Mini version for free at the Android Marketplace.
