This is understood. What I don't get is why a smartphone, with wifi capabilities, would need a femtocell to operate where there is already an available wireless connection in place. At the point where AT&T has worked out how to authenticate a call routed over the open internet as coming from your handset, isn't this extra piece of hardware they are charging us for superfluous?
I hope you choose to carry this story as it seems to be a case of AT&T blatantly profiting from customer ignorance and really shouldn't be tolerated. AT&T instead should release an AT&T branded VOIP app for it's iPhone handsets, instead of peddling additional hardware to it's customers when it should have beefed up it's wireless networks in the first place. Of course, the same could be said of others carriers and their respective smartphones, however, with the connectivity issues experienced by AT&T and iPhone users, I think this is particularly pertinent."
