Hi guys I came across something interesting the other day. I was having trouble with my iPhone (microphone not working) and I called up tech support and we went through the steps and we eventually got it working after a full reset. If the reset didn't work I was told I could send my phone in and pay $50 ( or around that) and apple would send out a replacement before they even received my phone But what got my attention was that if the reset didn't work I'd be able to post the phone back to apple and I could pay like $50or so and apple would post out a replacement phone before they even received my phone. I was wondering, if someone said their microphone was not working (but it was) and got the replacement phone and when apple checks the phone and sees nothing is wrong what would they do? Especially if they have already sent the replacement phone? Just an interesting thought.
