So I went to get my bumper on Saturday, something I was going to do anyway, regardless of the reception issue...I was just hoping to wait for the white one...
Anyway, so just to mess with the sales guy, I asked for a bumper because I could not make phone calls. He told me that they were not able to reproduce the issue in the store and wanted me to reproduce. I then just took my finger to bridge the gap between the two antennas. He then told me that, I should not hold it that way. I then showed him how I hold my phone, which also causes the issue. He told me how he held the phone.
I then asked him if Apple was going to have a iPhone class at the store about how to hold the phone. I think he thought I was an idiot, but he was being way too dismissive.
So I was cashing out and he was trying to use his portable payment system. He crashed. I told him that he must be holding the handheld incorrectly
I finished my purchase and walked out with my hand written receipt and all...their systems crashed.
