Apple Inc.'s (NASDAQ: AAPL) new iPhone could deliver a 55 percent return for every phone sold according to new findings conducted by market research firm, iSuppli.

In a tear-down analysis conducted over the weekend and reported on Tuesday, iSuppli said that hardware and manufacturing costs of Apple's latest phone amount to $265.83, generating a margin in excess of 55 percent on each 8Gbyte iPhone sold at $600.

The costs did not include royalties or other logistics, the firm said.

The tear-down revealed a number of supply partners, including Infineon and National Semiconductor, among others. Of all suppliers, South Korea-based electronics company Samsung was the biggest winner, however.

The electronics giant supplies the iPhone’s applications processor, which costs $14.25 in both versions of the iPhone. The company also contributed the NAND flash memory and DRAM for the iPhone.

Samsung has $76.25 worth of semiconductor content in the 8Gbyte version of the iPhone, giving the company a 30.5 percent share of the product's hardware cost—the largest total of any single supplier, iSuppli stated on Tuesday.

The iPhone, which combines phone, music playing and Web browsing capabilities, went on sale on Friday June 29.

With droves of people waiting outside AT&T and Apple stores when it went on sale, some analysts are beginning to believe the product will have unprecedented success.

Our sources indicate that iPhone will likely become the fastest selling product in AAPL's history and not to mention likely among the fastest (if not the fastest) in consumer electronics, Shaw Wu of American Technology Research told clients on Monday. We estimate sales of about 250,000 units in two days.

The previous fastest seller was iPod nano, which sold about 1 million units in about 17 days or, about 59k units per day.

Shares of rose $5.91, or 4.87 percent to $127.17 in Tuesday trading.
