Im thinking of returning my iPhone 4 to the apple store, if this cell signal problem is not going to get fixed. But whats the process done to get my micro sim out and get it returned to a normal sim? This is IF the problem isnt going to get fixed, and refuse to accept that this is a non-issue. I have the 14 day cooldown period to decide. I can always go back to my 3G and probably buy a 4 at a later date, but the problem for now is am I stuck with a microsim?
