“Failed to upload *.app on Device ” Error in iPhone

Question

I am getting an error while uploading my app on device. It does installs it but not able to upload it.

Also I want to run the instrument tool on device but when I run it

Answer 1

I was getting this issue on an iPhone running 3.0 software, but it was working fine on phones running 3.1. The app used to work on the 3.0 software until we added users to the provisioning for the app - this is the only thing I can think of that might have caused it.

If you're running 3.0 still, try upgrading to 3.1 and see if that fixes it.
