Error occurs when deploy my App to iPhone OS2

Question

Hi, I am a newbee in iPhone development.
I have met a problem when deploy my simple application to iPhone OS2.0
I create my app via XCode, by using the framework in iPhone SDK.(The SDK is the latest version, I downloaded several days ago)
After I succeed in deploying the application into the iPhone simulator,
I try to deploy my application to a real iPhone OS2.0
I know I need sign the binary before deployment,
so I create a certificate named "Test1" via "Keychain Access".
Then I add a "New Run Script Build Phase", contains the statement.
CODESIGN_ALLOCATE=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codes ign_allocate codesign -s Test1 -f ${TARGET_BUILD_DIR}/${EXECUTABLE_FOLDER_PATH}/${EXECUTABLE_NAME}
Then switch the project to iPhone Device / Release Version.
Build, no error
When deploying to iPhone, I got error,
Here is the detail from Console .

Can anybody help me?
Is it necessary to pay $99 at http://developer.apple.com/iphone/program/apply.html?
Is there any article tell me how to deploy step by step?
Thank you very much

Answer 1

Yes, it is necesery to pay the 99 dollars.
For that money you have access to an internet suite that allows you to create certificates.
These certificates are needed to test your software on the real device as well as deploy the software through app store
