“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

Sometimes manual delete of Build folder of your application fails to solve the problem "Failed to upload the .app on device"

Try WIndows->organizer->Provisioning profile(in left pane)->refresh it once....

This has solved my problem!
