the Java-based release for featurephones, the Android build of Opera Mini 5.1 (which, admittedly, also has its roots in Java) is ready for your browse-happy ways. As with the featurephone release, the focus here is almost exclusively on improving performance, an impressive goal considering that Opera Mini 5 was already burning rubber on many devices. Additionally, 5.1 is said to improve page layout on the latest round of high-resolution phones -- a good thing, considering many of us are now considering WVGA a bare minimum. Sickening thought, isn't it? The new build should be available to download from the Android Market today; follow the break for Opera's full press release.
