Tuesday?s Q&A session with Steve Jobs at The Wall Street Journal?s D: All Things Digital conference had some major implications for Apple mobile developers.

The most important takeaway ? Steve Jobs wants developers to succeed on the Apple platform. The Apple CEO wants developers to make more applications, make more money and grow the platform even larger.

Here are the main highlights from Mr. Jobs? interview that I thought were worth expanding on.

Analytics that do not ask for user approval are not allowed
Mr. Jobs directly attacked the data that analytics providers were collecting and publishing around mobile applications.

The fact that these analytics companies were able to pull information about new Apple devices and publish it really ?pissed? him off. 

Analytics companies give developers insight into usage, crash reporting, and location information.

Developers want to understand how users consume their applications ? essentially the same reason why people use Google Analytics on their Web sites.

Close to a year ago, mobile analytics companies such as Pinch Media, prior to merging with Flurry, provided developers with the ability to prompt users to opt-out of sending anonymous usage statistics.

The jail-broken community started its revolution to protect users and their privacy and worked with analytic companies to provide a clear opt-out mechanism. 

What you might not know is that many applications were outright rejected from Apple for asking users if they would like to send anonymous usage statistics.

The prompt never named the analytics company or what was going to be done with the data, but it did get user approval ? one of the main issues that Mr. Jobs brings up.

The referees that control Apple?s App Store approval process were not thrilled and just rejected applications, perhaps for the wrong reason. At that time, they may not have wanted third parties collecting any data though there was no clear policy on it.

Data providing advertising and monetization is OK ? developers need to make money
Apple learns more about the mobile advertising industry each day.

The company understands that advertisers have backend performance metrics and goals. It realizes that you need to provide data to advertisers to help increase CPMs and revenue for developers.

Mr. Jobs is OK with allowing developers to send that data back to mobile advertising companies.

The App Store is still dominated by paid applications.

Only 28 percent of applications are free. Most downloads and usage comes from this pool of significantly smaller, free applications.

Consumers are paying lofty bills for these next-generation devices and paying through the roof for data plans.

Apple wants to make sure the viral nature of the platform continues to flourish.

Much of the consumer usage is driven by free applications. The only way to incentivize developers to continue building free applications is to allow them to make money off of them. 

Apple is open to developers leveraging whichever monetization platform they want ? iAd is not required
Apple put a huge stake in the ground by forcing the mobile advertising community to further innovate on its mobile creatives by launching iAd.

The iAd platform is nothing new, however.

Mobile advertising companies such as Millennial Media and Jumptap have been producing similar creatives and rich experiences for years now. The difference?

Apple and Quattro Wireless are now promoting these new creatives to agencies around the country ? driving more awareness and dollars to the platform and helping generate more opportunities for all players in the market
 
Do you really think Steve Jobs would get excited with a 300x50 static banner running on the iPhone?

Mr. Jobs pushed the limits on technology by creating a device that changed the mobile industry ? now he wants to do the same for mobile advertising. 

IAd has driven agency RFPs to the seven-digit range and pushed the creative minds of mobile marketers, ultimately creating more money for developers and better user experiences for consumers.

At the end of the day, Apple wants to help push innovation in the mobile advertising space and maintain the rich consumer experience on its platform.

The company completely controls and essentially micromanages the application experience on the iPhone. But prior to the Quattro acquisition, Apple had no way of controlling the 300x50 or 300x250 pixels on an application.

Developers should be ecstatic. IAds might not be for them or their applications, but Mr. Jobs has made it very clear that Apple is not going to be the only advertising platform on the iPhone.

Other mobile advertising networks will continue to sell inventory across the App Store and exchanges will continue to help developers optimize across ad networks to make as much money as possible.
