I dont really understand , maybe it must be my Ipad 2 is maggic, as most of you while changing the screen digitizer I complety distroyed the antena next to home button, ( When I said distroyed , I mean it, is only a bit of the cable left the foam and chip is all gonne) so I was like shite now I lost my wifi, but still decided to test my ipad 2 and wifi works as good as before, the bluetooth is gone , so for sure that antena is just for bluetooth, so I just wont be bother to change it as I never use bluetooth.
Peace every one
