Anyone know if this is normal? Little past noon I noticed my iPhone 5 LTE drop to no service then 4G shows up. I have not so good LTE connection to begin with(2 bars) but since this afternoon I have yet to connect back to LTE(LTE is enabled). iPhone is a little over a week old, and this is the first time this has happened. My bro picked up his phone same time as me and his phone shows LTE connection. Should I be worried?
