    I read some articles on Android phones that use LTE on GSM vs. CDMA networks, and heard that some CDMA+LTE phones have lower battery life because the phone has to maintain connection with the CDMA network as well as the LTE network. Now, knowing that LTE doesn't transmit voice (yet, in the US), isn't this true for GSM+LTE too? And on top of that, if I'm on the phone and using data, does that mean my phone will use HSPA and not use LTE at all? Or is the LTE that's implemented with AT&T allowing LTE data and GSM data?

    Also, I've heard that many LTE phones show "LTE" in the menu bar but are actually showing the bars for EV-DO or HSPA. Anyone know what the iPhone 5 is doing?
