Ooookay... Thanks for the info, so I won't lose my time on trying to import my iap into Xcode.
Actually I've got perfect performance with intel XDK. Well, the game don't even run on an iPhone 4S (iPhone 5 minimum) so it limits the performance problem, but on the devices it runs on, it runs perfectly.
Now I eventually may be able to make the game to run on an iPhone 4S using Ejecta, so it's worth trying. However, I guess I read in a tutorial that Ejecta wasn't allowing interstitial ads. Is it true?
Store listing is still unsuccessful, outside of very, very basic tests, and only with C2 IAP (Phonegap IAP always fails even on very basic projects in which C2 IAP succeed).
I'll try to switch to another export mode (Ejecta) and see how it goes. Thanks for the reply!
