No, it won't, it might affect battery life a tad, but the actual notifications are very very small.

A badge is a little number that appears over the app's icon, like Mail or SMS. Turning these on lets the app post little badges on their icons to let you know you have new messages or something.

An alert is the pop up window that appears when you get an SMS, for example. Turning this on will let the app display these on the phone when it has something to tell you.

A sound is, well, a sound. Turning this on lets the app send out a little sound, like a ding or beep or something, just like when you get an email or message.

As an example, an IM app will use badges to show you how many IM messages you got while the app was closed, an alert will show a pop up box whenever you get a message. This will usually include some of the message and a button to go directly to the app. An IM app will use the sound feature to play a notification sound when you get a message.

Of course, apps can use these for all sorts of different things, a game for example could use the pop-up to notify someone has invited you to a multiplayer match.

There's no real harm to data for turning any of this stuff on, at least not with any of the currently available data plans, the only reason you'd want to switch them off is if you don't really want to be notified of those sorts of things, or are really concerned about battery life.

Cool, i just assumed it would have a data connection running constantly to achieve that result. I do want to leave them on for Facebook but wanted to make sure there is not a constant data connection. I have 3 gig data anyway so no biggy.

There is a constant data connection, but it's not sending much data at all, practically zero if there aren't any notifications. If you have 3GB, you literally won't even notice.

Yeah, they're pretty much exactly the same thing, just for different tasks.

Um, what?

As far as I know, the data connection is only invoked when information needs to be sent to the device, hence why it's called "Push" notifications.

Wait, I'm sorry. Wiki says "constant IP connection":

250 bytes per notification max. (a notification can invoke one or more methods (badge, alert or sound) at once as well)

Per MB you'll get at least 4000 notifications.

Ok i don't want to start another thread but perhaps someone can answer it here.
With facebook notifications you can turn the sound, badge and alert on and off in the (settings-notifications) menu but you can also set some more options in the (settings-facebook) menu like messages, wallpost ect . Does the first option in the notifications menu override the second lot of settings???

Basically setting the notifications in Settings/Notifications will set whether or not you get alerts, and the settings in the FaceBook app set what you will get alerts for.

So, if you have alerts off in the FaceBook app, but on in Settings, you won't get anything. The phone will listen for alerts from FaceBook, but FaceBook won't send any, because you told it not to send them.

If you have notifications on in FaceBook, but off in Settings, the phone won't even bother listening for FaceBook, and while FaceBook may want to send alerts, it won't be able to because the phone won't let it send any.
