Like I mentioned in your other thread on this topic, based on how Apple's handled issues like this in the past (i.e. the iPhone 4 isn't the first time they've launched a product that's had issues that generated this much discussion), they typically won't say ANYTHING until they've isolated the problem, come up with a solution, and have that solution ready to deploy.Both were nice but looks like Apple is taking the stance that "nothing is wrong" and I doubt they will fix anything.
That, plus their employees aren't supposed to speculate. If information isn't publicly available on apple.com, then you don't discuss it with customers. So until Apple does have additional information to share publicly, the employees are going to continue to say "hold it differently".
I don't agree with how Apple does this secrecy thing. But I also wouldn't say "I doubt they will fix anything", just because they haven't said anything more in the six days that this product has been for sale.
I'm pretty sure that the Apple employees know that the official company answer about the issue is stupid and wrong. So you show them the problem, then what? The only thing they can do is apologize that you're having a problem with your iPhone, and see if you want to return it. It's not like if you really really badger them, they'll give you the secret solution that they save for the customers that can physically demonstrate the problem?Go in again, bring your girlfriend's current phone as well as your iP4. When they tell you all phones lose signal if you hold them in certain places, challenge the guy to replicate the issue on the other phone, and show him that, as you hold it, the signal dosen't deteriorate.
