    First smartphone ever, Galaxy S2. My question is, does the phone automatically detect wifi and switch from the data plan to wifi once it's detected? Or do I have to go through my settings and manually turn off my data plan network, if so how do I do that?

    If I download apps when connected to wifi, am I still using up my data plan? I have a 5GB data plan with US Cellular.

    Thanks in advance everbody :)

    As long as WiFi is turned on, it will automatically use WiFi networks when they are in range. Any time it is using WiFi, it will not use your data plan.

    Like above have said... as long as your phone is actually connected to a wifi router, you will not use any of the data that is part of your data plan.

    A point worth mentioning in case you are not aware.
    If you leave wifi on all the time, it may well affect your battery life as it will be scanning all the time for a wifi point. The same with 3G as that will look for a 3g signal and if it can't find one revert to the normal phone signal. But after a set period will scan again for 3g and so it goes on.

    You can download various 'toggles' to your home screen and then just switch wifi and 3G on as and when you want them, that's what I do. It also helps cut down on your data plan use as well because the phone isn't constantly syncing with whatever apps you use - eg, facebook, Twitter, email, calendars etc.

    Y5 and some other apps will automatically turn on WiFi when in range of known networks and keep it off when out of range of known networks, eliminating the need to manually toggle.
