Hi just ordered my iphone 4 as been waiting for my current phone contract to expire. So, question is, has the so called aerial problem been sorted with new batches or do i still need to buy a bumper ready for when it gets delivered shortly? I am in the UK btw if that makes any difference and using the 3 network. I just wanted to know whether to order one or not or if it is not necessary now. Many thanks in advance.
