I currently have an iPhone 4 pre-ordered through Apple due to be shipped July 14th. My plan now is to try to pick up one tomorrow at WalMart and either go ahead and use it or sell it on eBay. I have two questions... 1. Will I be able to purchase an iPhone 4 for the subsidized price of $199 still? 2. If I decide to use the one I purchase tomorrow, what will I need to do to activate it? Do they activate it at the store or do I need to go to an AT&T store to have it activated? Thanks.
