Cause of the problem:

One more certificate was previously deleted in keychain (Keychain Access): Apple woldwide Developer Relations Certification Authority, which is the issuer of the iphone Developer certificate, If it is deleted it will cause the iphone developer certificate to be recognized as an unknown authority signature, and then the error will appear on the real machine debugging in Xcode.


Workaround:

Re-put Applewwdrca back in, download one from Apple's official website (http://www.apple.com/certificateauthority/), and drag it into the keychain (keychain Access)-Login directory.
