Using my developed application in my smart phone

I am very happy to use the MIT app Inventor, and i find it realy so helpful, but i don't know how to inport my finaly app in my phone, or how to publish it in the app store.

can you schedule to make a tutorial video on how can we make that?

If you look in the Ai2 browser  Guide, you will find many useful hints, including how to do what you want...  If you had gone there, you would have found

• Packaging & Sharing Apps

Hope you get it working...the instructions are not difficult.
