Have you read the Apple developer licensing agreements? (the ones you have to agree to before they'll even allow you to download the SDK) They specifically state exactly what libraries you may and may not use. Last time I read it (they update it frequently) they expected you to only use there own SDK and UI libraries. If you wanted to use someone elses, fine, but don't expect your app to get accepted into the iTunes store (so you can only run it on your own device + Jailbroken ones)
