How is everyone elses iphones doing with reception? I have been really shocked to see that the reception I am getting on my new iphone is worse than on my Razr! At home, I am only getting 3 bars, sometimes 2 and at work, I get 3 and sometimes 4. With my Razr, I ALWAYS had 4 bars and many times 5 bars. I am in a huge metropolitan area! I love the phone in every other way so far, but am pretty disappointed in the reception, especially since we were told that the plastic back would help with it! How is everyone elses reception? Better or worse than before....whether a previous iphone user or not?
