[iPhone] unexpected error (0xE800003A) - installing app to device

Question

Hi, I'm running into the "Your mobile device has encountered an unexpected error (0xE800003A) during the install phase: Verifying application" error while trying to install and run my app on my iPhone
Here is what I've verified
[1]. On my iPhone, Settings->General->Profile shows the Developer Provisioning profile I created on the developer program portal.
[2]. In XCode, Info.plist has the bundle identifier set to "net.companyName.AppName" (AppId on the dev program portal is magicNumber.net.companyName.AppName"
[3] Keychain Access shows a "Apple Worldwide developer certificate" and a "iPhone Developer: FirstName LastName" certificate". for the iphone developer certificate, it also shows a "FirstName LastName" private key.
[4a]. In XCode, after clicking Info icon for the project Target, I verified that "Code Signing Identity" and the next row ("Any Iphone OS device") are set to "iPhone Developer: FirstName LastName".
[4b] "Code Signing Provisioning Profile" and the next row ("Any iPhone OS device") are set to the developer provisioning profile mentioned in [1].
When I do a clean Build, I get a dialog that asks "codesign wants to sign ............"
However, if I attempt to "Build and Go", I get the 0xE800003A error message mentioned above.
Does anyone have suggestions on what trouble-shooting steps I can take to identify and fix the problem
Btw after running into the device installation problem mentioned above, I'm now running into problems with the simulator as well.
After a clean build, I tried to run the app with Active SDK set to the simulator.
However, now I get a "Failed to launch simulated application: iPhone Simulator failed to install the application." error. So I'm not even able to run the app in the simulator anymore.
(Btw I have the 2.0 SDK on my Mac. My iPhone has 2.1 on it. I'm assuming that this is a supported configuration.
I haven't installed the 2.1 SDK because I want to make sure that my app only relies on the 2.0 SDK and can run on 2.0 iphones.)

Hi, I've answered this on another thread, but I'll repost here... I think I may have encountered a simpler solution.
Rather then edit the Info.plist directly, you can use XCode to do this for you. However, your mileage may vary, this is only what worked for me!
The docs seem to be missing a couple of steps.
After you have edited the build info for your application (accessed by selecting 'Targets > APP_NAME' and then hitting 'Info' in the Xcode main navigation bar) click the 'properties' tab of the Info panel. Here you should see a number of fields (Executable, Identifier, Type, etc...).
By default you will see the Identifier field populated with the following: *com.mycompany.${PRODUCT_NAME:identifier}*, by simply changing this to *+your.domain+.${PRODUCT_NAME:identifier}*, your.domain being the domain you entered when you created your provisioning profile, you should be good to go!
So for example, say your company is +acme.com+, change your identifier to:
*+com.acme+.${PRODUCT_NAME:identifier}*
If like me, you also have a wildcard provisioning profile (I named mine general), you might use something like this:
*+com.acme.general+.${PRODUCT_NAME:identifier}*
This, of course, relies on you having created an App ID named +com.acme.general.*+. This is the profile I use to experiment with the Apple example apps.
Hope this helps someone!
