[barrykflau88]

I brought my Iphone 4 with 3 network a month ago.And having NO SERVICE a number of times.I bring it back to apple store to have a look at it.Then they exchange a new one to me just yesterday.But just within 24 hours it happen the same problem 3 times,even worst.No matter I move to where,it still could not having reception back.Every time I do is turn it off,and turn it back on,then the problem fixed.And I don't think I'm in the blind spot area.
Is anyone having the same problem like me,or can somebody tell me how to fixed this .It's pretty annoying.
Cheers

Take it back to the store if it's a disturbing issue. A hard or software issue again.

Yes yes, why not? They can change it 10 times until you have a good working iPhone, it doesn't matter how many times they change it, what matter is if it's working well or not.
