provision file error in iPhone OS 2.2

Question

I created an AppID "MyApp", DeviceID "MyDevice" in Program Portal and I downloaded the provision file and drag it to Organizer, downloaded the .cer file and install it on Mac.

All these works fine, but when I build my app, an error pops up saying "CodeSign error: a valid provisioning profile is required for product type 'Application' in SDK 'Device-iPhone OS 2.2'".

I tried to find PROVISIONING_PROFILE in project.pbxproj in myApp.xcodeproj, but it returns "Not Found". What might be the problem? Do I need to modifiy the info.plist and what should I modify?

The provisioning process for developing iPhone apps can be very confusing, and your error could be due to any of a number of issues. Here is a very thorough walkthrough:

I would suggest totally scrapping whatever provisioning profiles you have, erase them from XCode, and start over using this tutorial. That seems to work the best in most of my cases.
