Anyone had any issues with 4G reception? I've been finding I'm getting 1 bar of 4G reception in my flat - I'd expect better as the mast isn't far away. I get full strength 3G reception.
Maybe it's time to contact Sony...
Why do you think you should have good 4g coverage on the basis you get 3g?
Why do you need to ring Sony because your provider doesn't have decent signal in your area?
