I want to somehow find reliable information about whether I should upgrade to a 4s from a 4, or if I should go with another phone entirely. The issue is reception. With Rogers in Vancouver I have terrible, unacceptable reception issues. I drop calls, can't hear people properly, they can't hear me properly, sometimes my phone doesn't ring when someone is calling me, and other issues. I have had my iPhone 4 replaced with a new one by the apple store, and I still Have the same problems. I need to change to a phone that works properly. Can someone telle About their upgrade from 4 to 4s with Rogers in Canada? Was there an improvement in reception? Thank you for your time.
