Counting down the best iPhone apps made in Australia.

With tethering controversies, device shortages and now its very own virus, one would have to say 2009 was the year of the iPhone explosion.

Apple's iPhone now accounts for 17.1 percent of smartphone sales worldwide, according to Gartner's Q3 2009 market figures.

Despite Australia's generally overpriced and underpowered mobile data networks, local firms have developed some of the world's best mobile applications. Aussies have embraced the iPhone and local developers have produced a wide range of useful, entertaining and popular apps.

Some target the local market with apps that let you find out about the weather, what's on TV, or how much you can download before you hit your ISP's quota. Others have set their sights on the world with games, productivity applications and useful guides.

Here, in alphabetical order, are six locally developed applications making waves in their respective fields.
