Running App on iPhone4 from Xcode fails

Question

I have a problem when running my App on my iPhone from Xcode. The App runs (seemingly) fine in the simulators (iPhone, iPad, etc). It also runs fine when loaded on the iPh

Answer 1

It turns out it was a code signing issue. A while back I was having problems adding an iPad 3 to my test devices for Adhoc distribution, and I changed the code signing in trying to make that work. That was an iOS distribution certificate and I had to now change that back to a developer certificate to run the iPhone from Xcode. What is clear from this is that I really don't fully understand the whole code signing and distribution process.

But it works again, so great.
