Pocket PC: Generally speaking, tennis sims for mobile devices are pretty lame. Fiddly controls and jerky animation are often the main culprits in the failings of these titles.

What are we expecting from the Worldwide Developers Conference in June? Lots of people are predicting that Palm will launch their much hyped Pre handset on June 7th, just a day before the Apple conference begins. Maybe Palm are hoping to overshadow any Apple announcements, but that looks dangerous to me, as Apple are likely to have some cool stuff up their sleeves.

Here at OnSoftware we've been wondering out loud what might happen, so starting with the most likely things, here we go:

1: Snow Leopard. Surely there'll be an exhibition of the next version of OSX, 10.6, which sounds like it will build on what is already my favourite operating system. The most interesting thing about it for me is that it will have an overall smaller hard drive and RAM footprint (like Windows 7) - efficiency is always a good thing. We know that Windows 7 is lighter so it can work on netbooks.... Probability: 100%

2: The next surest thing, and it's a pretty sure thing too, is an announcement of a third generation iPhone. What's it going to be like? I wouldn't expect much of a visual difference (it won't be available in pink any time soon), but should do the things people think it should already do, like video capture or maybe a compass (like the HTC Magic). Perhaps you'll be able to alter the backlight time too? Reading that back, maybe Palm are right to gamble, or maybe Apple have something really cool for the next gen iPhone? Probability: 90%

2.5:  Rumours abound that working with Verizon, there might be an iPhone lite in the works, and some have claimed to have actually seen the device. It's worth remembering that Apple went as far as creating fake prototypes to keep people from knowing the truth about the original iPhone... I think an iPhone lite is a pretty underwhelming concept too. Probability: 30%

3: Mystery item! With all the stories about Apple ordering 10 inch touchscreens, Snow Leopard being easier on resources and the success of netbooks in general, there are many predicting Apple will announce something between a Macbook and iPhone. Tim Cook, Apple's COO recently said that netbooks "suck", but that could be a precursor to "but ours are cool". Bets are divided between some kind of netbook or keyboard free tablet device. The 10 inch touchscreen tablet sounds like a sweet idea - a device for browsing and watching media. However, in my head that looks like a big iPhone, which shows a lack of imagination on my part! Probability: 50%

We've seen numerous alleged photos of Apple netbooks, or Macbook minis, but none of them look convincing (or good!)!

*thanks to our resident Apple insider Tom for the secret Apple iPhonebook image!

Windows: Reinstalling the operating system is a pain, especially when you come to the part where you have to search, download and install your favorite apps. With Smart Installer Pack you can avoid these three boring steps and install your most frequently used utilities in a snap. Simply click on its icon and the installation will start right away.

Mac: Ever wondered if really is a solid free alternative to Photoshop? The Gimp allows you to retouch, author and edit your photos thanks to a wide set of tools and the best thing of all is it's absolutely free. All the essential tools are here including clone, airbrush and pencil features plus a powerful gradient and blend tool. If you're looking for a free image app, you can't do much better.

iPhone: If you're a student, a writer, or just a keen Scrabble player then check out Dictionary.com's excellent iPhone Dictionary & Thesaurus. The free app delivers reference content from Dictionary.com and Thesaurus.com, including more than 250,000 word definitions and over 80,000 synonyms. Best of all, all of this data comes bundled into the application so there's no Internet required!

We've all met those people who think they're pretty cool just because they've installed a funny ringtone, a sexy background wallpaper, or a stupid animation on their mobile. More often than not they will have paid a small fortune to download it from a premium rate service, too. However, the smartest of smartphone users turn to theme-creation software to customize their phones for free.

Nokia's Series 60 Theme Studio is perhaps the most powerful product of this kind. It's free, and with a bit of creativity, you can produce much better designs than those crappy themes you see advertised on TV and in the back of magazines. Although the software is very powerful, it does have a reputation for being a bit of a beast to use. I've taken the opportunity to provide a quick guide to using Series 60 Theme Studio. It's by no means a comprehensive walkthrough (that would take you about three months to read) but it should help you get started and give you a grounding in this somewhat daunting application.

1. Start by downloading Series 60 Theme Studio Carbide. Once installed, run the program and select a folder to save your work to, when prompted. Click OK then select the Create Theme option from the Welcome screen.

2. Give your theme a name in the New Theme menu and make sure the default S60 Theme template is selected. Now to change the background wallpaper. It's best if the image you use is already sized to the dimensions of 360 x 640 px. The image I used here came from VectorStock (it was free). To apply the image as a background, click the Idle preview window in the Gallery. Highlight the image in the main window then look for the Image icon in the Layers window. Right-click on this and choose Select File. Browse to the folder containing the image, select the one you want to use and hit OK. In the Background option inside the Resources panel, highlight Active Background and repeat the above procedure.

Symbian UIQ: We've had bird flu, mad cow disease and elephantitis, and now another seemingly cute creature is set to bring terror and panic to the planet - the Ameobax. This mutant germ has escaped from a scientific lab and is spreading its way across Earth in the form of a series of cuddly blobs with big eyes. Don't worry it's not real, apart from in this excellent mobile game.

Mac: Being able to see the person you are communicating with makes such a difference to the quality of your conversation and reduces the feeling of distance of those that are far apart. The problem is that most IM clients only allow one video at a time. ooVoo however allows you to see up to six friends, family or colleagues at the same time, in very high video quality and all for free.

Windows: Growing tired of that old Windows XP look and feel? Try something different with the SevenVG RC Windows 7 Theme, a visual theme that will give your Windows XP a complete overhaul, making it look like the brand-new Windows 7.

Mac: The Dock is in my opinion one of the best features of OS X but it doesn't come with any alternative templates and styles. That's where Dock Library steps in to provide you with several different templates and looks for your dock which can be activated in a click.

Windows: Evri Toolbar brings the semantic web to your browser. What's that? Well, you get much more intelligent search results, multimedia content, related terms and much more. It's still only in beta, but it looks fantastic and makes a Google search seem very last year. It's especially good at things like bands and names of people, although it's a bit weak if you search for "table"!

iPhone: Ever wished you could tap into your iTunes library on your computer using your iPhone? Well, Remote allows you to do just that - and more! Remote gives you the power to control not only the music on your computer, but also on your Apple TV. This is all done using your iPhone or iPod Touch. The application is able to handle playlists and lets you browse your complete multimedia library.

Mac: If you're creative when it comes to icons, then try Opacity for size. Opacity covers three graphical areas for icons - applications, icons and the web. It offers the traditional pens, colors and zoom tools. You can use some of the templates to get working right away or start from scratch by selecting one of the different shapes and create your own interfaces, buttons and much more.

I'm particularly fond of image editors and I've tested many of them, including all those online editors that have become so trendy in the last few months. But I must admit I've never seen such an incredible online image editor as Sumo Paint.

This amazing tool opens up in your web browser and displays a complete Flash interface that will look amazingly similar to Photoshop. This reduces the learning curve to almost zero to all those who are already familiar with Photoshop, but if this is not your case, don't worry: you'll get the knack of it in almost no time.

Sumo Paint includes a full featured tool menu with pretty much anything you need to start painting from scratch. Brushes and pencils are designed to draw just like the actual tool, trying to be as realistic as possible. You can customize colors, fiddle with opacity and flow percentages and of course, work in different layers.

 When it's time for photo editing, Sumo Paint doesn't fall short of expectations either. The program lets you load images from your local drive, an Internet URL or your Sumo account and apply a dozen filters and effects or adjust color and brightness values to it in a couple of clicks. Should something go wrong, simply press Ctrl+Z and it'll be undone – just like any desktop tool!

Regarding those Sumo accounts I just mentioned, don't get me wrong here: you don't need to register or sign up for anything to use Sumo Paint. It's totally free. The Sumo account is only a way to enter the Sumo community, a group of Sumo Paint users that have gathered around this great online editor and share their photos and drawings online. Having a Sumo account therefore lets you upload your own creations to the Sumo site and also comment on what other people have uploaded.

I could only find one drawback to Sumo Paint: the program doesn't include a proper Help section yet. Photoshop users don't need it, but other people would find it quite handy. In all, Sumo Paint is an excellent online photo editor that's really worth a try.
