I've yet to be able to connect to 3G on my 3GS phone since getting it yesterday. I've been trying all morning in downtown Denver and last night in Boulder, all places that have full 3G coverage, according to AT&T's website. 3G is enabled in Settings>General>Network. Is it supposed to connect automatically, or am I missing a step? Thanks!

    My problem isn't as severe as yours, but mine stops working after a period of time, but when I reboot the phone, it works again. The WiFi is fast when it is available.

    I experience a similar problem with the 3G service on my Apple iPhone 3GS. The 3G connection will disappear after a while. And it has to be re-enabled with a reboot of the iPhone 3GS.

    I had wondered if this represent a hardware problem for my iPhone.

    I experience the same problem even upgrade from iPhone 3.0 to iPhone 3.1 today (3Gs). The problem happened randomly when I try to use the 3G network. I've tried to turn off the 3G and turn on again and does not work. It has to be turned off the iPhone to get it works again.

    Hi All,

    I just fix (I don't know if this is a right word) this issue by reset the network settings to default. The problem has gone for almost two weeks. The 3G service works everytime and the system seems much stable. If you have experienced the same issue you might want to try this.

    Goto Settings -> General -> Reset -> Reset "Network Settings"

    Note: It will clear up all WiFi profile
