Re: Apple Podcast app not using WiFi

I currently have 2 iPhones, both of which use the PodCasts App. They share their data via iCloud, and they both have the "Settings"->"Podcasts"->"Use Cellular Data" set to "off". They both keep the list of several GB of podcasts current, and so far, neither device has used more than 600MB of Cellular Data (download only), and both have used over 4GB of wifi.
One thing to keep in mind that when you have an iPhone disconnected from the external power, it will turn the wifi radio off a short time after the screen sleeps, so when you think you're connected to wifi, you aren't really. For me, my iPhone 4 is in a Mophie Juice Pack Air, so it thinks it's always on external power, and my new iPhone 5 is on AC power all night every night. My iPhone 5 has only used 477 MB of cellular data in the 12 days I've had it (and it has used over 7GB of wifi).
I don't know if the iPhone 5 will use LTE over wifi if you have slow wifi and fast LTE. It is possible that it is using the fastest connection available. When I am at home, I have 12 Mbps internet connection, and only "4G" cellular data, so my wiofi is generally faster. At work, I have 100 Mbps wifi, and very weak AT&T cell service ("4G", 3G, and occassionally Edge), so the wifi speed there wins too. I haven't tried connecting to a Starbucks where I also have LTE coverage to see which is faster, and which is used. It is possible that it might use the LTE over the slower shared wifi...
