Wondering when the next new Iphone will be launched? Rumor has it that the new and upcoming ‘iPhone 4G’ will be launched along with Steve Jobs’ keynote at the Worldwide Developers Conference 2010 on June 7 at 10 a.m. For the meantime, Walmart is currently on an clearance sale of previous iPhone units (iPhone 3GS and 3G), beinging down the price of the iPhone 3GS with a 2-year mobile contract to half or $97. Whether a purchase of the current iPhone units will be a bargain or not is still with the consumers. They can grab the price cut or save for the upcoming 4G iPhone that is said to be priced within the $199/$299 range.
