How to get the internet connection on my iPhone 4S to work?

I got an iPhone 4S today and when I wasn't logged into a Wi-Fi network, the internet and some of my apps didn't work. When i went to some of my apps, they said that there was no internet connection found and needed a network connection. On Safari, i was told that i wasn't connected to the internet.

do iPhone 4S' need a Wi-Fi connection in order to work? I don't have Wi-Fi at my house. Do i need to send the iPhone to someone in order to fix the problem?

Turn the Wi-Fi off for 10 seconds and turn it back on.

You need Wi-Fi (internet) to get internet. You could use 3G but it will use your data. Get internet otherwise your iphone is somewhat useless. Also read the quicstart guide. You seem new to this.

  • Wireless internet connection won't work on any device? My broadband connection works just fine, but the wireless connection won't work. All the devices I;ve tried are two laptops (Vaio) an iPad, and three iPhone 5's. When this happens, I usually just turn the router of and on again, but that won't work. I've connected my laptop to broadband to ask this question, by the way. It's on and all the devices can see it, but when I try to join, they say unable to connect. I don't have a password
