I do a lot of streaming radio in my car, and I couldn't help but notice that when LTE is being accessed there is a faint buzzing static sound that can be heard through my car speakers, This stops when I switch to 4G. I never had this with iPhone 4 on 3G. Kind of reminds me of the data buzz you would get on Edge, but not nearly as bad. Has anyone else noticed this? Maybe a limitation of LTE or possibly hardware related?
