Wall Street extended its love affair with Apple Inc as strong iPhone sales allayed concerns it was losing market share in the cut-throat smartphone market, with analysts again rushing to raise price targets on the shares of the world’ most valuable company.

The iPhone 5 rumors keep coming.

Apple’s upcoming smartphone will come with a 4-inch screen, due mainly to a thinner, taller body, according to Apple-focused site iLounge, citing an unnamed source. The site’s source claims Apple’s new iPhone will be 10mm taller than the iPhone 4S, and about 2mm thinner. By keeping the same width and tossing in the display to fit the new form factor, Apple is able to deliver more screen space than what’s available on 3.5-inch-equipped iPhones, according to the source.

Although the front of the iPhone 5 will look about the same, the back will feature a flat, metal panel stretching from beneath the camera to nearly the bottom. iLounge’s sources did not say why the device might come with that additional element. Aside from the metal panel, the device will boast Gorilla Glass 2 technology, according to the site’s source.
