Alright, since some of you have had a theory here and there about whether Apple has addressed the antenna issue with new batches of phones, I wanted to go ahead and see if there was any truth to this theory. The forth and fifth digit for this phone is 28. So, based on other threads, I would say this phone was made in week 28? Is that correct? I do not notice any changes on the phone. There is no difference on the metal band that surrounds the phone from my previous one. I will be sending this one back because it seems there is dust inside the camera, which is odd considering these replacements are supposed to be new and not refurbished.
