hi all, just want to get an idea, how many times have you had your iphone replaced? i'm currently on my 3rd unit. first one (new) had a microphone issue, had that replaced, then the 2nd unit had a wireless issue, and replaced. i am on day 2 with my 3rd unit. it was made on 2009, 24th week. 2nd unit was 2009, 20th week. can't remember the first one.
