yes
no. facebook is located on the internet.
Apps such as Facebook and Twitter use your internet. If you do not have a internet on your tariff you might consider getting one or using a WiFi network
you need the facebook app if you want to instantly get to facebook, and that is free in your app store, but you don't HAVE to have the app because the iPhone should automatically come with internet so you can click Safari (internet) and also get facebook from there.
It depends on the app. Most games don't require internet, but apps like Facebook, Safari, email, and others do.
If you have an iPod touch then yes. Download the (free) Facebook app, or just use the Internet( whichever you prefer. )

The messenger app is already in facebook, you can use it if you want to.
No, you cannot. Since Facebook is on the internet, you must have the Facebook app and a wireless internet connection (via a wireless router) to access Facebook.
Vizio internet apps work very well and are slowly becoming a very popular app to have for the internet. This app allows you to use social networking sites(such as Facebook and twitter), stream music and surf the internet.
You can download a free app from the iTunes store. To use it, you have to be in a wifi area which allows you to get on the internet.
No not really. Messenger is an independent app, you can work with it even when you dont have facebook app.
To access your Messenger on Facebook, you can either use the Messenger app, which you can download from your device's app store, or log in to Facebook on a web browser and click on the Messenger icon. If you have the app, simply open it and log in with your Facebook credentials. Ensure your internet connection is active, and if you encounter any issues, you might need to reset your password or check for updates.
