Hi, I know this has been asked a lot but I can't find anything on the 4s. Just wanted some advice, basically my 4s has issues with the flash bleeding on to the screen and constant signal dropping. I contacted Vodafone UK and I was told i would be provided with a replacement by courier. The lady did tell me that it would come in a sealed box with all accessories etc and would be 'new' but is there any chance it could still be refurbished even if it was sealed in original packaging? Thanks!
