As research group Gartner expects (right) the mobile advertising market to expand by 78% to $1.6bn in 2010, Apple has been showing off its new smartphone OS that features an advertising platform and it has also stronger-than-expected sales of more than 450,000 iPads.

The iPhone 4.0 software is available on Apple's smartphone this summer, complete with upgrades, including a multi-tasking capability. iPhone's OS is also used on the iPad, and the newest generation of software will come to Apple's tablet this autumn.

The new iAds allows applications developers to use advertisements in their apps, pocketing 60% of the revenue, where Apple will sell and host the ads.
 
Since the iPad went on sale, users have downloaded more than 600,000 digital books and 3.5m applications for the device, Jobs (left) has said, and there are already 3,500 apps available for the iPad.

There are also already more than 830 video games developed to suit multi-touch screen, as well as the nearly 25,000 iPod Touch and iPhone games that will also play on Apple's latest gadget clearly aimed at gamers.

Twitter at Chirp

The Twitter acquisition providing a mobile and desktop client for itself has been grown by the news that it has helped Research in Motion build an “official” Twitter app for BlackBerrys.

Twitter which focused on its Web site, leaving development of Twitter mobile clients up to start-ups like Tweetie, Twitterrific and UberTwitter for Blackberry devices, now seems to be moving with dedication toward building or buying more Twitter service apps, with developers being recommended to focus on business tools, analytics and gaming.

It has already acquired its search engine Summize and Mixer Labs which helps developers build location-based services.

With Atebits or Tweetie  founded by (left) Loren Brichter, a software developer who used to work for Apple on the iPhone and sells for $2.99, is the most popular mobile Twitter client last year, winning an Apple Design Award. Twitter will now offer it for free, renaming it Twitter for iPhone.

On the Mac computer version, Tweetie runs ads from Fusion Ads network. Twitter has said that it will consider some sort of advertising in the near future.

As the official Twitter developer conference Chirp swings into full throat on Wednesday and Thursday in San Francisco, it should be an interesting dawn chorus.
