failed to install on iPhone

Thanks for your help guys. I have solved the issue already and the problem is about the certificate.

Again thanks for your help

Be sure that you are using a provisioning for testing, there are like 2 provisions you go through when testing///then ad hoc/app store.  This took me like days of frustration to figure out; it's kind of inobvious imo

If you've changed provisioning files, make sure you make a cleanup on the project, before compiling a new ipa-file, or you can bump into this error message.

I can't say for sure because a lot of stuff can go wrong with the whole identification and provisioning process, but one thing I can say for sure: download the iPhone Configuration Utility (http://support.apple.com/kb/DL1466) to install your application instead of using iTunes.

Also, in my experience, the utility won't install anything on your iPhone using Windows if you are on iOS 4 (you'll need a Mac if so). Otherwise, you're good to go.

Especially check out the console after a failed attempt because that's where you'll find more info.

If the file name is the same as the bundle ID, then presumably the bundle ID is something like "MyGame". If it's "com.MyCompany.MyGame", then that as a file name would seem wrong.

If it is "MyGame", check the App ID. If it is like "812763814.MyCompany.MyGame", or "812763814.MyCompany.", it would most likely fail. If it's "812763814.", then it should work.
