• RSS Mobile reader : Now you can subscribe to your favorite RSS news feeds on Opera Mini, and all updates are just one click away. You can sort articles by feed source or by date.
• Photo Upload : Share a picture from anywhere, anytime with your phone using Opera Mini's photo sharing feature. Upload your photo to a blog or forum, or as an e-mail attachment.
• Advanced Secure Browsing : Do even more online with Opera Mini. Secure connections will now let you safely use secured sites, such as your e-mail, bank site, online stores, with no exposure of your personal details.
• Automatic Content folding : The content folding feature shrinks lengthy menus to save your scrolling thumb. You can easily inspect the block of hidden content by hitting the [+] button next to it.
• Faster Browsing : All subsequent requests to a server within a session are now quicker. Opera Mini keeps an open connection between server and client reducing overhead TCP set-up times.

This is not all, because Downloading is the biggest feature in Opera Mini V3 that I was missing in the previous ones!! Now you can download images and files to your mobile handset, the case of image is a little different where you can find lot of features to zoom, resize and download any desired fragment from the images.

I think now Opera Mini will invade the browser market, as a free powerful solution. Hope to see it integrated with more mobile phones in the future. But I'm not sure about the future of Opera Mobile, since it's now in real competition between its rival Opera Mini.
