iPhone 4S Newbie Question: Using WiFi automatic over 3G?

Hello.

I have an iPhone 4S newbie question with its wifi and Verizon 3G. How do
I make a new iPhone 4S automatically switch over to wifi connections
when available instead of using Verizon 3G that have data caps? It is
annoying to switch between them manually through its settings. I assume
there is a way to do this automatic. Basically, wifi preferred when it
is available. A prompt to switch between them would be nice too
especially with untrusted wireless acesss points (WAPs) and 3G caps.

Thank you in advance.

iphones automatically prefer wifi. you only need to join a wifi network
once, and with a password if required. it will save that information
and rejoin it the next time you are within range. there is also an
option to auto-join any network it sees but you don't need to enable
that if you want to only join known networks.

If you have both WiFi and 3G turned on at the same time the phone will
choose WiFi as its first priority, if available, and only use 3G when
it is not.

I leave both WiFi and 3G turned on all the time, with "Ask to Join
Networks" set to "OFF". My phone automatically connects to known WiFi
networks as I move around and only uses 3G when no known WiFi networks
are within range.

Thanks! But why let your iPhone to autojoin any new/unknown wireless
acceess points (WAPs)? They should be untrusted due to possible security
breaches (hackers, sniffers, etc.).

if you disable ask to join networks, it will only join the ones to
which you have previously associated.

Um, it autojoins only known WiFi networks. If it's never joined that
network before, it asks.

However, all networks with the same name are considered to be the same
network. So, for instance, if you join Apple's customer network in an
Apple Store, you will autojoin the network in any Apple Store.

Similarly, if you join a network named "Linksys", you will autojoin any
network named Linksys so long as they are not password protected or have
the same password as the one you manually joined. This can be dangerous,
but it's highly unlikely that there will be any adverse fallout.

Ah OK. Good and thanks!

Ooh, that's bad. I am surprised it doesn't check for MAC addresses. I
know they can be spoofed, but still!

That would be unproductive, all but the smallest wifi networks have
multiple MAC addresses and multiple access points serving a single SSID.
