It's funny I came here to mention how the handshaking from constant dropped connections and cell location changes should be accounted for. I've had to consolidate multiple calls into single calls in order to increase the network performance of mobile applications. It wasn't until I actually sniffed what was happening that I noticed the handshake issue as I walked around, went down into the subway, hit alleys, etc.

As for prefetching, I think that should be a user setting. I've had to pre-fetch and cache data because the content was enormous and the backend was out of my control. But I do agree that a user should be able to decide themselves how the device uses resources and I try to push this into every app. Give the user a choice if they feel inclined.
