Windows Phone 7.5 devices are now available in Japan and Russia, and with several new phones announced this month, now is the time to submit your "Mango" enhanced app if you want to be there when customers take their first big bite out of Mango.
"The rate of apps submitted that take advantage of new Windows Phone features like fast app switching and multiple live tiles is steadily increasing," stated Todd Brix over at Windows Phone blog.
Brix in a September 20 blog post on Windows Phone blog said that "by the end of October we will enable functionality in App Hub that will allow you to publish updates to both the 7.0 and 7.5 versions of your apps."
Adding, "Knowing that on average people update their apps every three to four months, this October timeframe provides assurance that you that you can submit 7.5 apps today and still have access to your 7.0 app well before the next update is required. There's no need to wait!"
Brix also recommended that you identify the Windows Phone 7.5 functionally of your app in both your app description and (if needed) in the screenshots. "To make this easier for you and your customers, we've designed and are making available today screenshots and overlay graphics that you can add to your own screenshots to identify your app as optimized for Windows Phone 7.5 (examples below)," said Brix.
These are the only screenshot text overlays that will pass certification. These new standard artwork resources are now available here and will be accessible via App Hub shortly.
