Hi all, Anyone knows what is the difference between point (1.) and (2.) as I listed below? (1.) After submit Iphone apps to Apps Store: Using development provisioning, release, run and install my Iphone apps into an Iphone device. (2.) After submit Iphone apps to Apps Store: Using distribution Ad Hoc provisioning, run and install my Iphone apps into an Iphone device. I have another question, that is if I already submit the Iphone apps using distribution (with Apps Store selected) to AppStore, can I still use development provisioning to run, install and test our Iphone Apps on an Iphone device? Or I must use distribution Ad Hoc provisioning to run and install my apps into an Iphone? Any comments and suggestions are appreciated. Thanks a lot.
