iphone stockCreating more speculation that Apple will introduce a new iPhone model on Monday, AT&T is now out of stock of the current iPhone. Online Apple store and many of Apple’s retail outlets have been running out of iPhone stock for several weeks. With no iPhone available either from Apple or AT&T, it is now clear that they are this close to introduce a new model.

At the same time, iPhone prices are going crazy on eBay. Some 16GB unlocked listings are currently carrying “Buy-it-now” prices over $700, which represents a $200 premium over brand-new models purchased from Apple or AT&T.
