rev-a pissing me off!!!!

[dbord_n]

ok so i got a question if the signal and tower say i have rev-a should i not have rev-a?? they just upgraed the towers in my city and at my house where i use it most the signal shows rev-a but there is no change in speed. when i drive 2 miles to my wifes office i get an average of 1.7mps with spikes of 2.5 and that is inside a hospital.at home in the driveway with the same ammount of bars and everything i get an average of 700kps with spikes of 1.2. what gives???? do they "upgrade" some towers and not others and if so why does it show rev-a?? any help would rock my brothers!!!!
