i know u want to say that im rude right? but im not.. im saying the truth. Deggie told that im in fringe area. and i said im not in fringe area. im apple product user. expecially iphone product. i was using iphone 3gs until the latest iphone5. so i feel the problem and changes. im doing with some experiments;
now i have an iphone4s and iphone5 too. Both devices are 3G indication at the top of the screen. And then i disabled the 3G and re-enabled it. The result: Iphone 4S turned from 3G to E and immediately turned to 3G. unfortunately, iphone5 turned from 3G to E and nothing change after that. Of course i did the experiment in same place at high and excellent coverage.
my brother using iphone4s, i asked him to do the same. and the result was best for iphone4S. And i asked my sister which using iphone5 to do the same. the result was same (no indication 3G after E).
and my conclusion, this is not carrier problem. of course the device problem whether iOS or hardware.
i am appreciate users who attempting to help me. unfortunately you thought that i was going to take offense to other users attempting to help me? we are apple product user from all over the world and English is not my mother tongue. so sorry to say if my tone was rude-like. hope u understand with your attitude too. Thanks
