Very frustrating calling the stores. Firstly you have to hear a message about buying your iPhone from your favourite Apple store and they'll help you choose the right airtime package and setup the phone. Then you hear 'There are more than 8 callers ahead of you'. By the time you get through, if there are any devices you probably wouldn't make it to the store to get one!
When I was in one of the stores, one of the store employee said to me that they know when they're getting deliveries but they can't say because of security reasons. Not sure if true or not but struck me a little odd because there are more expensive items to steal. Also, when the scalpers were out in full force, they were all paying cash. Surely that is a greater security risk than attempting to bulk steal iPhones which would be useless if Apple track serials?
