$30 isn't much when talking about something as expensive as the iPhone, but every little bit helps. Because of changes at work (i.e. no more free blackberry) I had to get a phone/service today. I went to Cingular and signed a two year contract and bought their cheapest phone. It is $30. But, I get a $30 rebate AND, according to the salesperson who knows I plan to buy the iPhone, I can return the phone I got today within 30 days and get credit torwards another phone, including the iPhone. I get the credit even if I got the rebate. The only way I get hosed is if the iPhone comes out after June 23rd. Again, $30 ain't much, but it's essentially free money.
