By now you should know what does 3G means, but no, you still don't know. No, it doesn't stand for three giant network or third generation phones. All you need to know is that it is a wireless network, unlike Wi-Fi, it is in the air with little radiation. Sorry, unless you are wearing tin-foil, then you can't escape from it. Anyway, it is almost fast as Wi-Fi, so it is a data delivery service. After all the confusing words, 3G is finally coming to USA for T-Mobile in the limited cities. I really can't wait, could this be the iPhone killer? Because Google is going to release the Android OS to phones and T-Mobile is getting first. The release date for 3G data delivery is October 1. iPhone users step aside, here comes T-Mobile 3G in Portland.
