    If I'm at home or somewhere else that has both Wi Fi and 3G available, how do I tell which one my iPad is actually using at a given moment? I'm at work now and there's a free public site listed next to Wi Fi under Settings but it says AT&T 3G at the top in the black bar. Does that mean it's using up 3G time instead of Wi Fi which I obviously don't want?

    Also, in Settings under General>Usage...are the numbers next to "Sent" and "Received" my totals for how much 3G I've used up?

    Yes, the usage indicates how much 3G has been used.

    As to whether 3G or wifi is used. If you are connected to both, then wifi is used. So if you see both the 3G signal bar strength and the wifi strength (the volume like symbol)m than wifi is used. If however, it only shows the vertical bars, than 3G is used.

    Keep in mind, that the iPad auto connects to known networks, but it doesn't automatically connect to unknown wifi networks, not even if they require no password.

    OK, under "Choose a Network" I chose the Free Public WiFi and it's listed next to Wi-Fi under settings but I only see the signal bar strength and AT&T 3G at the top. Does that mean I'm not using the Wi Fi network? If not, how do I make that happen?

    What I normally do when I'm using Wi-fi I turn off the cellular data and when I'm not near Wi-fi I'll turn it back on and use the cellular data

    There is absolutely no reason to do this!

    If a wifi signal is present and the ipad is connected, it will always use this over a 3g connection. Even if the 3g is a stronger/faster signal.

    I guess it would save some battery by disabling the 3G raddio altogether though... Not something that I would do myself, but I can see folks who are worried about battery life disabling 3G when not needed...

    Although, if you disable the 3G radio, then you wouldn't receive any phone calls either, right??

    That is correct. Not that I receive all that many phone calls on my iPad, even with 3G on, but hey, who knows, maybe someone figures out a way to add Phone to the iPad :D

    As was recently discussed in a similar thread:

    When the iPad is awake, it uses Wifi over 3G, but when it is asleep, it uses 3G over wifi. This is just something to keep in mind, when leaving 3G on all the time.

    I did end up turning off the 3G while I was at work because I didn't want it using up too much of my 250MB allotment as we'll be going out of town later this week and may use quite a bit. I had signed into a Wi Fi connection when I first got in, or at least thought I had. So I'm not sure when or why it switched over to 3G.

    I think turning it off can be useful if you're using it while doing other things and don't want to keep looking to make sure it hasn't dropped Wi Fi and switched over to 3G on it's own without you noticing, if that's possible.
