Joshua Topolsky over at This Is My Next is reporting on a mock up of the next iPhone based on his sources. Look at that mock-up and think about what is being rumored here. Then ask yourself, how does a phone that thin, or even as thin as the iPad 2, have respectable battery life and include the power hunger global CDMA/GSM chipset and retina display as well as something at least as powerful as the A4 chip?

Color me skeptical on this one.
