According to investment firm Susquehanna, Apple is expected to sell 111.4 million iPhones in 2012. Apple's latest iPhone 4S is the main reason for the increased sales forecast. The new model's popularity was obvious during the first days of the phone's availability, with the handset breaking many sales records. The investment firm had previously predicted that Apple would only sell 104.4 million iPhones.

Apple has finally unveiled its new iPhone and it's not an all-new iPhone 5, but an upgraded version of the iPhone 4, which despite being a significant improvement resembles a bit of a disappointment to Apple fans. In fact, Apple's share price actually dropped following the iPhone launch event.
