And it has a new app to help developers track their App Store sales too.
Apple has officially opened its submissions process for apps that use the features of its new iOS 4 software.
Developers have been emailed inviting them to submit their updates or new apps now, to ensure they're available on the App Store when the software goes live for iPhone and iPod touch owners.
CEO Steve Jobs announced during his WWDC keynote this week that the software will be made available on 21 June as a free upgrade for all users.
It will also be pre-installed on the iPhone 4 handset, which goes on sale three days later.
One of the key features of iOS 4 is the ability of non-Apple apps to run in the background, using Apple's new multi-tasking APIs.
People will be expecting a decent number of apps to support that new feature from day one, so Apple's approvals team will presumably be working overtime to make sure as many multi-tasking apps make it to the App Store for 21 June.
Jobs claimed that 95% of submissions are approved within seven days, although that will be put to the test now, if the iOS 4 updates flood in.
In seperate news, Apple has launched a new app called iTunes Connect Mobile, designed to help developers keep tabs on their App Store sales.
"You can now view your daily and weekly sales data related to updates, paid and free apps as well as In-App purchases," explains its App Store blurb.
The free app is available here.
