In a new report, the Wall Street Journal says that Apple, the electronics company, will not be recalling the iPhone 4. The publication, which cited a source, says that Apple's engineers had been aware of the risks of the new design as far back as a year ago. However, the insistence of Steve Jobs, Apple's CEO, on the new antenna design caused the company to go ahead with development.

The source adds that Apple was so secretive about the iPhone 4's development that the device was not subjected to tests that would have exposed such problems. The test units that the company sends to its carrier partners are said to be "stealth" phones, which have different shapes and functions compared to the phones that eventually get sold on the market. The test phones were designed to keep the phone from being touched, says the source, thereby making it difficult to discover the iPhone 4's issues.

Apple is also said to have given its carriers limited time to test the iPhone 4 before the model was launched in June 24. The company earlier released a software fix for the iPhone's signal bar display, which is said to show the wrong amount of signal strength.

In an earlier report, Bloomberg News says that the company's senior antenna expert had spoken to Jobs about the antenna's design leading to dropped calls.
