I pre-ordered and am already using my iPhone 4 for personal usage, so this has nothing to do with me. But.. My friend stood in line today to get iPhone 4 and plans to sell it on eBay. He previously had a 1st generation iPhone so he is under the impression that if he bought this new phone under contract ($499 early upgrade) that he could stop paying the $15/month fee after one month since he will no longer have the iPhone 4 anymore after he sells it on eBay. With the 1st generation, he was only able to remove the $15/month fee at will because the phone was no longer under contract or not sold under subsidy. So my question is this, won't AT&T charge him a cancellation fee or continue wanting the $15/month on the family plan for the iPhone 4 because he signed a 2 year extension for his line on the family plan? Otherwise how will they get their money back for the subsidized phone? Let me know.. I tried to find details of this on the Internet but couldn't find the exact link with this wording to show him because he doesn't believe me.
