So where I work there are VZW 3G & 1XRTT repeaters. I tried out the RAZR HD and it latches onto 1-2 bars of 4G and is virtually useless. No data, no nothing and I can't get it to switch to 3G which obviously I'd get full bars.

I was wondering if the iPhone 5 is better at switching to the stronger signal in the area? Or if it's radio would act the same as the RAZR's...any 4G signal takes priority?
