I had this working great for a while. Until today when I bought a few apps on the app store and sync'd. Now XCode won't run my app on my device at all. It gives me the 0x8E0000... error. I've rebooted my computer and my phone multiple times, and double checked my certificate and compilign settings and all looks right. 2 things that make this bizarre: * I have another app that I can run on the phone fine right from XCode, using the same settings and certificates. * I can build the app, and install it in iTunes via an adhoc provision, and sync and the app shows up just fine. What the hell?
