we have had our free iPhone app on AppStore for a month or so, and we are now updating it. In our update we have added a lot of support for new stuff, i.e iPad-support, and it’s a pretty heavy update. In our existing app, we have a lot of ads everywhere, and we now want to upload this new version as a ‘pro’ version alongside the other one insted of updating the old one, giving the users a choice between the old free ‘ad-filled’ app, and the new $0.99 ‘ad-less’ and upgraded app. We are still using our same Xcode-project, and we are wondering if we need to change any app-identifiers or provisioning profiles or notification keys or anything like that? Our push-service is to be used for the same to both apps, so if we don’t have to add an extra .pem etc, we don’t want to..

to have different apps (been “lite” and “pro” doesn’t mean much on AppStore) you need different identifiers and so different provisioning profiles.
the easier way is to create a new target in XCode cloning the existing one and then modify it.
I’ve no direct experience related to the push part, but I suppose different provisioning ends in different .pem
