Does anyone know what would cause an “app signiture not valid” error when syncing an app on your device. This is the same app (just a new version ) that was installed previously. The only change i believe is that I updated the Itunes version on the mac. Anyone have any ideas. I even set up a new provisional to see if that would fix but it did not. Thanks.

If you’re using an AdHoc provisioning profile and certain it’s not an App Store one by mistake, then the suggestion that your signature is invalid, when previously it wasn’t, is a tad confusing.
I’d suggest opening Xcode and viewing the provisioning profile you used to build in there; does it have any warning type messages when you click on it? Or a message “Cannot be installed on devices”?
If not, if your device name in the list that appears below it?
