Here's why, apple missed the mark when a new phone wasn't released in time for many people eligible coming from an iPhone 4, Many people anxious to upgrade and many who probably have some held off to see what the new iPhone had to offer. That time has come and many are 50/50 about it. In the past Apple had two new carriers introduce the iPhone bringing in new sales but now most people on sprints network aren't eligible and probably aren't willing to pay full retail. Many verizon customers aren't eligible as well so this will definitely cut into sells. Sells will be great but I don't think they will be as big of a gap as previous releases.
