Apple Inc.’s new iPhone 4 costs almost $20 more to make than its predecessor, the iPhone 3GS, but the device will still help the company continue to rack up high profits, the research group iSuppli said recently.

The iPhone 4 went on sale June 24. After taking this latest Apple gadget apart and identifying the components, iSuppli estimated the cost of the parts totals $187.51. That’s more than the $170.80 iSuppli estimates for the cost of the materials inside the iPhone 3GS, Apple’s last-generation smart phone.
Chief executive Steve Jobs hails ‘most successful launch in Apple’s history’ despite reported problems over phone reception
Apple says it sold 1.7m iPhone 4s in its first three days, a record for the newest version of its top-selling product, and the company could have sold more but for production constraints. The latest model features video calling and an updated body, although some users have reported problems with reception, apparently due to a design flaw.

Steve Jobs, Apple’s chief executive, called the iPhone 4’s launch “the most successful in Apple’s history” but added: “We apologise to those customers who were turned away because we did not have enough supply.”
Research in the US by the analysts Piper Jaffray and in the UK by AQA suggests that 77% of iPhone 4 buyers queueing outside stores on the first days were upgrading from previous models – implying that 23% of buyers were new to the platform.
