I was playing around with the Skype app this weekend thinking how good this app actually worked. I then thought about AT&T femtocell that still hasnt been released. Yes, yes I am aware that it is a rip off for the customer. I totally agree with that point. I was thinking that apple should look into developing technology that could switch to Wi-fi when in range as seamlessly as phones currently switch from edge to 3g. I know this would be a very difficult endevour but I think one that would have huge benifits to both AT&T and the customer. AT&T would get less network congestion and wouldnt have to produce and sell equiptment to customers to make up for crappy network service. The customer would get more reliable phone service with a clearer call stream.
