Hello! @jojo123456789 thanks for your interest in submitting new ideas!
If you have an idea for a U-Verse app, we ask that you go to /support/faqs/u-verse-enabled-faqs#how-to-submit-app and enter the U-Verse onboarding/application management portal. If your idea is for a wireless smart phone app, please visit us at /support/faqs/att-developer-program-and-api-platform-faqs#how-can-customers-get-my-app to submit your app to the OEM Storefronts and platform vendors, such as Google Play, AppStore on iTunes, Windows Phone Store, HP AppCatalog, or BlackBerry AppWorld.
Hope this helps!
