The launch of the iPhone 3G S has helped Apple’s App Store to power to 1.5 billion downloads.
Just four months ago, it was announced that one billion apps had been downloaded from the store.
The subsequent surge in demand is thought to have been driven in part by last month's arrival of the new edition of the iPhone.
Apple’s decision to release the figures comes in the week that rival mobile phone manufacturer LG confirmed plans to open its own app store to European consumers later this year.
However, Steve Jobs, chief executive officer of Apple, has dismissed suggestions that competitors’ application markets would present a serious threat to the Cupertino-based company.
He said: “The App Store is like nothing the industry has ever seen before in both scale and quality.
“With 1.5 billion apps downloaded, it is going to be very hard for others to catch up.”
Available exclusively on O2, the iPhone 3G S packs in a faster processor than earlier editions, HSDPA support for fast downloads and a 3.2 megapixel camera.
