iOS Beginner Developer - Need a Little Help

OK...I have the latest Xcode SDK installed on my Macbook Pro. I have updated my Iphone to IOS6. So now I'm trying to set the Iphone so I can run apps that I develop on my Iphone. I went to the IOS Portal and ran the Provisioning Assistant. However, when I build my little hello xcode app it fails becasue xcode says the appid is wrong. I've included 2 screen captures to illustrate the problem.

So my questions are

1) How can I change the current provisioning profile to allow this app to run on my iPhone? The app compiles and runs just fine on the Iphone Simulator.

2) Are there videos out there that show this process in detail?

Oops...sorry!

Here are the screen shots.

Also...to cure this problem...I went to the IOS provisioning Portal and generated an AppID that had the correct name and then downloaded that and installed it to Xcode. Don't know if that was the best way but it worked. The app...simple as it is... now runs on my Iphone. (Gotta start somewhere)

So I guess that brings up another question. Do I need to do this for each program I write or what?

Jim

Ya know....I'm sure that for an experienced developer, my question must seem like childs play. I read the docs on how to create a wildcard AppID. HOWEVER,
when I go to the IOS provisioning portal and fill out the provisioning screen,
it REQUIRES me to select a specific AppID, I cant just type in *. Thus my confusion.

I'm sure Apple wants to protect their product/brand but this process is very frustrating to say the least!

Jim

Thanks to all who replied! I took a look at my provisioning profile and it
had a different name than the bundle ID in xcode. So I went into Xcode and changed the bundle identifier to match the appID in the provisioning profile.

That is:

Prov Profile Name AppID
TestingIOS KJCY49ZT57.com.learnIOS.*

In Xcode:

BundleID
com.learnIOS.HelloNoun

Now it compiles and is sent to my iPhone! Yeah!!!
