I say call and order insurance right now if you dont already have it. then in a day or two head to your local sprint repair center and have them test it. if you have insurance take it in tomorrow. thats why you pay for it.
Cause yeah the speed in my sig is from my apt. which is made of brick. my calls cut in an out in certain spots, but i can usually get a strong signal. the 1015 is my highest yet, but i would say i average 600-700kb/s
