Hey guys, I just had my iphone replaced with a new one two days ago by apple as my old one developed a fault with the dock connector...apple were nice enough to replace mine with a new set even though it was 2 months out of warranty...my mobile phone provider O2 told me to get lost basically but apple were very understanding.
Anyway, I did the test again and this time with this latest Iphone I am getting -58 on the signal test. This is the best reading I have ever got. It might be that on new sets Apple have improved the internal design slightly. Whatever it is, the signal quality is better.
I am going to get the Iphone 5, after having the Iphone 4 for more than a year and the fact that Apples service is EXCELLENT, I am going to stay loyal to them!
To be honest in the past 14 months since I had the Iphone 4, I had less than 10 dropped calls. I've had other phones which were about the same.
