During the pre-order fiasco I was able to place an order for an iPhone 4 16GB. A few hours later I received 2 confirmation emails with seperate order numbers. I checked my credit card and I was charged for two subsidized phones. I'm considering putting the second up for sale on eBay. Is there anything I need to be careful about because I was charged a subsidized upgrade ($199)for both phones? Will a new line of service be added through AT&T or will they just charge me for a non qualified upgrade price for the second phone $699.
