At what point in the video clip does the signal completely disappear knocking the phone off the network? I watched the whole thing, and only saw a signal decrease.
My HD7 does show a lower signal when I hold it, but I can't make a call drop or internet connection disappear.
Though I do find it funny that an iPhone site would pick up on a story that even XDA developers doesn't seem to care about - where real owners post on their device, not iPhone users trying to point out that their phone isn't the only one that sucks.
