Opera Mini 4 delivers a fast, impressively advanced user-friendly experience with this upgrade to its mobile phone browser. Keypad hot keys speed up zooming and scrolling. The browser comes with a familiar mouse. You can create your own search shortcuts, synchronize your bookmarks with your other Opera browsers, and alternate between rendering views. There's also a landscape mode activated by pressing the "#" and "*" keys, just not for BlackBerry phones or a few others. Other limitations exist, as well, most notably that Opera Mini isn't compatible with every carrier and model, so you'd best check the specs first.
