It seems that everyone will be able to have a look at the fourth-generation iPhone this summer—without having to find it in a bar. Reports claim that it will be unveiled June 7 at the World Wide Developer Conference, where Apple CEO Steve Jobs is slated to give the keynote address. It is widely believed that the 32GB version will go on sale at $199 and a 64GB will hit stores at $299. Meanwhile, Walmart is making the third-generation version even more accessible by slashing the price of the 16 GB model to $97.
