Guys / gals I just spent the same as most of you, hours and hours waiting for shipment, refreshing, looking out the window for Fedex etc. etc. Got it, read about the lame antenna issue, went and bought a case, and after all that here is my issue! going from a 3G to the 4 my battery life is horrendous. 100% to 35 % in 5 hours while making 5 5-10 minute phone calls. I do have wifi on as at home I am on my wireless server, screen brightness set to 50% push mail set to hourly. When I check under the General Tab and network I see it trying to tether but I cannot find a way to turn tethering off completely as it's now supported anyway. Bluetooth is off! Somebody give me some advice, Please By the way, have done many searches to no avail!
