Are you a customer if you've consumed in the past? The iPhone 2G and 3G still have all the functionality they were sold and advertised to have. Any future OS updates are above and beyond that. Before the iPhone was released in 2007 I don't remember any significant OS updates being common on SmartPhones sold in the US. Usually you had to resort to hacked ROMs lifted from newer devices.
