Android Client: 3G vs WiFi and Last.FM

[ecd1973]

Having a strange issue with the Android client. If I play songs on Android over 3G, the server registers what I'm playing and scrobbles it to Last.FM. If I switch to WiFi on the android, the server no longer scrobbles to Last.FM.

All else being equal, why would connecting to WiFi disable the Last.FM functionality?
