Opera Mini fan blog

You may already know bookmarklets can be used on Opera Mini. At least I have tried to do my best to advertise WapReview article 'Bookmarklets for Opera Mini' by Dennis. Using bookmarklets is possible because Opera Mini support javascript very well. Therefore you can use javascript also in bookmarks like listed at http://o.yeswap.com

Now that Opera 9.5 for desktop browsers is finally officially released it's also time to give a few advices before you rush using it together with Opera Links and Opera Mini 4.

Once you have taken the new Opera browser in use, just select 'File > Synchronize Opera...' from menu bar. Then, when you open a new tab on Opera 9.5, you get the same speeddials as you have on your Opera Mini 4 browser's start page. Moreover, you get access to all your other Opera Mini bookmarks via Opera 9.5 bookmarks, and all your Opera 9.5 desktop bookmarks will be accessible via Opera Mini 4 browser's bookmarks page.

In my last (and, now, heavily outdated) article on making Opera Mini 4 be invoked on by just clicking a URL, I’ve already elaborated on the advantages of doing this (and, actually, the advantages of Opera Mini 4 itself). Please do read it if you want to know why making use of direct invocation can be really advantageous.

Because there’s a lot of news worth reporting on (and I’ve been asked by Serola to join the Opera Mini Fan Blog as the first blogger, because of which I've decided to update this really important tutorial) and the original article didn’t elaborate on other mobile platforms like Symbian and BlackBerry, I’ve decided to devote an entirely new article to this question.

Opera Mini users on Windows Mobile / Symbian / BlackBerry, attention: you will NOT need this all-in-one Bible in order to “just” make your Opera Mini work. Your best bet is following my Opera Mini 4.1 review HERE. However, if you want to learn all the secrets of running MIDlets on your handset (for example, to reassign buttons to make scrolling much-much easier) or you also plan to run other MIDlets and want to know everything about the compliance, speed etc. issues, this Bible may turn out to be REALLY useful.

Also note that this Bible does NOT discuss Java applets or applications. For more info on running applets under Windows Mobile, see the Web Browsing Bible; for application-related info, see my generic Java articles.

You may have already heard at least of Java games (more precisely, MIDlets) running on almost all current “dumb” phones. These games are all the rage today, especially with teenagers, which also means there are thousands of sometimes really high-quality games for ordinary phones, all written using the portable Java language, ready to be played on (almost) any kind of mobile phone. Just an example: in THIS HowardForums thread, the topic starter post lists some (but not all!) games available for the Samsung QVGA 240x320 phones (d600, d900, e900 etc – not only Windows Mobile ones!). Quite an impressive list, isn’t it? And it’s just the tip of the iceberg – there are a lot more games, all waiting for you to purchase, download and run!

No, don’t think MIDlets are only for gamers and are absolutely useless otherwise. You can make a good use of them in the enterprise too. There are several solutions already for, for example, mobile payment, reservations etc. done using a MIDlet as opposed to the Web, which is, in a lot of cases, is much harder to access / operate on a small-screen device. Controlling for example your bank transfers via SMS can also be less intuitive and/or require a lot more work / data entry than using a GUI to do this. Other, known enterprise-related MIDlets are Jupiter, which is basically a financial data streaming program (also see THIS) and Betfair (also see THIS). Should you be interested in these “MIDlets in the Enterprise” questions, I really recommend Michael Juntao Yuan’s excellent book “Enterprise J2ME: Developing Mobile Java Applications” – I’ve learnt a LOT from it. Highly recommended!

(Note that this article not only discusses Opera Mini but also a lot of other browsers. Even if you aren't really interested in them or have an OS not covered (for example, a dumb / feature phone), it will give you a decent overview of how Opera Mini 4.1 compares to the alternatives. Sorry for the size - particularly if, as recommended, you follow the references.)

As has been announced some weeks ago, I had a W3C speech a week ago devoted to Web browsing on mobile devices. You can find the (English) slides HERE. (Sorry, some of the example screenshots are in Finnish. This, however, doesn’t have a detrimental effect on the overall understandability of the material.) In order to understand the slides, I’ve also decided to comment on all of them so that the entire Windows Mobile, Symbian and BlackBerry mobile community can benefit from my speech – in written form. Finally, note that, albeit this article is over 80kchars long, it in no way can provide a FULL, absolutely thorough overview of the Web browsing scene on these platforms. That is, if you don’t understand something, don’t despair: in my referenced, previous articles, you can, in most cases, find a very thorough dissemination of the subject. Just an example: in this article, I only devote some 2kchars to the subject of downloading files while my original, devoted article, along with its (recent) updates, amount to over 100 kchars.

I also provide in-line screenshots in this article so that you know what I'm speaking about without constantly switching to PowerPoint; however, to see the original document at its full (and copy/pasteable) glory and resolution, you'll need the PPT file.
