We witnessed the iPhone 4G roar take place and a few days back even saw a white iPhone prototype appear on several websites. The leaks appear to be coming from Apple’s manufacturing unit in China.

These facts already make us somewhat sure that Apple is going to announce its iPhone 4G at Worldwide Developers Conference (WWDC), to be held from June 7-11 at San Francisco. Need some more proof? Walmart has reduced the price of iPhone 3GS to $97. Looks like a clearance sale to make way for the new product. The 100$ price drop almost confirms the arrival of an iPhone from Apple.

Hope it will be as magical as the iPad.
