I have no practical experience with Android, but in iOS I've not seen any of these problems. And if Android's best answer to 2G/3G latency is to turn a ~70 byte APRS packet into a few hundred characters of XML, I'm going to burn an extra stick of incense at my shrine to Steve Jobs (all us Apple Fan Boys keep one in our homes) today in thanks!
