Steve Jobs' Open Letter to iPhone Owners ($100 Store Credit Offered)
Jobs defends the price drop but acknowledges the need to take care of early customers:
... even though we are making the right decision to lower the price of iPhone, and even though the technology road is bumpy, we need to do a better job taking care of our early iPhone customers as we aggressively go after new ones with a lower price. Our early customers trusted us, and we must live up to that trust with our actions in moments like these.
As a result, Apple will be offering every iPhone customer a $100 store credit towards the purchase of any product at an Apple Retail store or Online Store.
Details will be posted next week.
