the 3G signal was good, I am in my house, the 3G speed by where I live is pretty fast. the highest that I have gotten using 3G is 1.74 Mbps for downloading and 1.1 Mbps for uploading with a ping of 410 ms. My highest with wifi is 4.8 Mbps for downloading and 0.58 Mbps for uploading with a ping of 112 ms.
if it is way to slow, I am going to talk with apple.
