How to Run Instruments with Real Device

You can start profiling your application by pressing Command-I (that's i like in India). By default Xcode4 Instruments runs on simulator.

When you want to profile on a real device: select at top left corner Scheme popup menu, "Edit Scheme...", Profile MyTest.app and change Build Configuration from Release to Debug.

Check what is Info.plist Bundle Identifier, go to Apple iOS provision portal and download related App ID provision file and install. Note that if you're not Team Admin, you have to ask someone else to download the file for you.

Actual error code shows also cryptic mobileprovision id, but that won't help you much:
