Before you ask .. yes I have browsed this forum and others.. No.. I haven't dropped it in water.. Yes I have air cleaned and brush cleaned the dock port.. no, it's made no difference. Firstly I got the prompt which asked about airplane mode which was beginning to drive me nuts. As far as I can see there is no way I can disable this pop up notification... I installed newest software upgrade last night and now I get the message above. Similar thing.. different wording.. This is just as annoying (but at least it doesn't activate airplane mode if I accidentally touch the "yes" button as before !) What I want to know is will Apple accept that this is a fault with the phone ? I was about to buy another two for family members but until I can fix this fault I'm pretty reluctant. SURELY apple can issue a FIX which disables this prompt???? which, as far as I can see, does nothing but annoy people?
