I've recently bought B4i and have been playing around with the aim of seeing if we want to transition our apps to multi platform not just android.
However I haven't bought an Apple Developer License yet, and I consistently get mobile provisioning errors when trying to run on the local mac builder with simulator... I was under the impression this didn't need the license ?
Check settings in IDE menu. Tools - Device IP address: Simulator should be marked 'F2'. Tools - Builder Settings - Server settings : check Server IP / port
