...remember the supposed reception issues of the iPhone 4? My iPhone 4 had far better reception than this phone, especially of wifi signals in my home.
Moving the headphone jack to the bottom is gonna be a real problem for Mophie and other battery case designers. I depended on Mophie to give me enough battery life to make the iPhone worth it. We shall see how they solve this problem.
Siri is often unresponsive in my iPhone 5, often hanging on routine requests like "call Mama at work." Even Windows Mobile from 5 years ago had better voice integration.
I have a somewhat significant iTunes media commitment that will require migration if Apple doesn't fix these problems. So far I'm beyond disappointment to pure aggravation.
