Application could not be verified error when building app for iPhone device

OK, I've just got myself a shiny new MacBook Pro, and having been developing my iPhone app on another MacBook, I wanted to migrate my development to my new computer.

I've got to the stage where I can build the app and run it on the simulator no problem, but when it comes to running the app on my iPhone, I keep getting "The application could not be verified". I have installed a new developer certificate, and installed the provisioning profiles (all generated new), but I'm at a loss as to why I should still be getting the error.

Anyone have any ideas as to where I'm going wrong?

EDIT

I've recreated the certificate and profisioning profile, etc... The Build succeeds, and the status at the bottom gets all the way to 'Installing on Device', then two modal dialogs are displayed with the same "Application could not be verified" error message.

Is there any output I can get to that will give me a precise error?

EDIT

OK, I've got the appropriate log from Organizer showing the problem. It looks like I haven't set up the Entitlements.plist, but in xcode, I have. (I've added an Entitlements.plist fole, then unchecked get-task-allow, then added Entitlements.plist to the project settings under Code Signing Entitlements). The log is:

Can anyone shed any light on why this isn't working as expected?

EDIT

Got the build working, but I've not accepted an answer yet, as I have no idea as to what's going on. Anyone with any idea as to what is going on?

My problem was actually that I already installed the app via a testflight on my phone, after removing the app it worked!

I got it resolved by deleting already installed build from phone and then reinstall the build.

From this thread on ADC:

get-task-allow, when signed into an application, allows other processes (like the debugger) to attach to your app. Distribution profiles require that this value be turned off, while development profiles require this value to be turned on (otherwise Xcode would never be able to launch and attach to your app).

Check if your iPhone properly provisioned. You may connect iPhone and launch Organizer from XCode (Main Menu -> Window -> Organizer) and then check PROVISIONING PROFILES information.

After that you need to match Bundle Identifier (Project -> Info.plist) and your App ID. You may read this Apple Note Mismatch between App ID and Bundle Identifier

I had similar message boxes (two in a row) when my Bundle Identifier was incorrect.

Did you remember to expand Targets on the left of the project window, then right click on your app name > get info, then go to the Build tab and under Code Signing, under Code Signing Identity, change the value of Any iPhone OS Device to what applies in your case? Also in the properties tab you should have your identifier set so that it matches the identifier you chose.

Don't know if that helps, that's the step I found missing in your description though.
