According a study released earlier this month, Apple’s iOS is becoming the most popular platform for enterprise app development – with 53.2% of developers picking iOS for corporate app development compared to 37.4% of developers standing behind Android. RIM’s BlackBerry, the old guard of enterprise mobility, came in a distant fourth behind Windows Phone with only 2% of developers supporting it.

That’s great news for Apple and the iPhone and iPad in business and enterprise environments. Apple even makes enterprise distribution possible outside of the App Store. Mobile App Management (MAM) and enterprise app store solutions provide efficient and effective distribution and update methods for enterprise apps.

Business to business (B2B) apps and solutions, however, present a different kind of challenge – one for which Apple has a solution, even if it isn’t a perfect solution.

In an email sent out to iOS developers today, Apple has announced a new rule that requires all apps to be submitted for approval with high resolution 1024 x 1024 icons and artwork. That’s a higher resolution than the display built into the iPad 2 — for an icon.

While popular iOS games can make their developers a small fortune in the App Store, not every title is a huge success. With over half a billion iOS apps currently available, some are bound to go unnoticed. However, one developer is attempting to make money from his iOS game in a different way.

With his latest game struggling to take off in the App Store, indie game developer Adam Schwartz is looking to bring in some cash by selling the title’s source code on eBay.

Apple has sent an email out to developers with the reminder that the annual iTunes Connect shutdown is scheduled for December 22nd-29th. The iTunes Connect portal shuts down every year during the holidays while Apple’s corporate employees take a much-deserved break.

The shutdown means there will be no app updates, price changes, or submissions approved for the App Store during that timeframe. This year’s shutdown lasts two days longer than previous years.

Apple began emailing iOS app developers today to tell them all about a new “auto-ingest” tool for retrieving iTunes connect Sales & Trends data. The new tool is Java-based and will run on any operating system, giving developers quick and easy access to their daily or weekly sales reports.

Until today, App Store promo codes were only redeemable in the U.S. iTunes Store, meaning those of us in other countries and without a U.S. iTunes account were unable to take advantage of promo code distributions and giveaways.

Apple has now made developers aware that promo codes are no longer limited to U.S. customers, and that they can now be redeemed in any App Store.

Your promo code distribution is no longer limited to U.S. customers. Promo codes in iTunes Connect can now be redeemed by all App Store customers worldwide. Your Team Agent can request 50 codes per version of your app in iTunes Connect and your customers can redeem these codes in any App Store. To learn more about requesting promo codes in iTunes Connect, see the iTunes Connect Developer Guide.

An interesting rumor floating around today suggests that Apple might be using the holidays around Thanksgiving to migrate its iTunes services to their huge North Carolina data centers.
