After seeing more rumors than we care to count, we can finally lay this one to rest: the pple has tweaked the antenna location and removed the SIM slot for the CDMA iPhone 4, but things seem mostly unchanged feature-wise from the GSM version. It's worth noting that the mute and volume controls have been moved down slightly, so some of the current iPhone 4 cases might not fit properly. The Verizon iPhone 4 has a newer version of iOS (4.2.5) with a "Personal Hotspot" option, but it's unclear whether this is exclusive to the CDMA model.
