What is the "App Id" that the Apple developer connection site is asking me for?

Question

I just signed up to be an iPhone Developer. What is the "App Id"? Is it my company name? Is it just my application name? Apple isn't very clear on this.

Thanks.

Its a namespace for your applications. For example:

com.myname.MyCoolApplication

it uses a reverse domain name sort of format with the idea that only 1 person owns a domain at a time. You can make an App ID that is a woldcard like:

com.myname.*

And now you can replace anything in the spot of the * creating a suite of applications.
