Does anyone know if the 4s or 4 can be switched to evdo only mode.  I live in a fringe area and the 1x is stronger then evdo.  I currently have a palm pre which can switch to evdo only and it helps when tethering.  I was hoping that the iphone would be able to switch to evdo only, so I can use it to tether.  Any help would be greatly appreciated.
