Newly introduced to the Android Market is Opera Mini 4.2 which has been especially made for use with the Google Android operating system, although as with most new applications and software it does still have a few bugs.
With the new Opera Mini 4.2 for Android come some highlights which include changeable skins and a “speed dial” feature which gives the G1-er a grid of popular windows whereby you don’t have to open your bookmarks every time.
Opera Mini for the Android is unique in as much as rather than download a web page to your Google Android T-Mobile G1 and then rendering it, Opera Mini renders the page on its servers and then sends to the G1 and thus reducing load time.
