The iPhone is not the only smartphone with antenna issue. #CellularCountry believes that all smartphones have the same sentiments. Well, that all depends on your grip.br br The HTC Evo, for instance, has also a weak spot when it comes to antenna issues and signal. Fortunately, it is at a place where nobody would bother to touch, hence the signal issues is not a problem. This is because the antenna of the HTC Evo is found somewhere near the top right part of the phone (when the screen of the cell phone is facing the user).
