Will you get push notifications for your email, fb, msn, twitter app, etc when your SGS is in sleep mode?

How do you control your notifications on the SGS? is there a notification menu in the settings like in the iphone?

Can you turn on and off your notification settings from that notification bar?
Is the push notifications on the SGS reliable and fast? Have you guys encountered notifications which come in late? Or do they normally come in to your phone promptly?

Does anyone have the hotmail email account working on the SGS?
How is it on the phone?

I have a few quetions,
1. Can this phone read microsoft word attachments, and powerpoint attachments from emails? Also, can you edit it on your phone?

2. When you have a new comment from fb, or a new tweet, or a new IM from msn, do you have to go into the app itself to see the new notification, or will the notification automatically appear in the notification bar?

3. And lastly, can you put up a full facebook widget on the TW UI, instead of the semi facebook widget?

So meaning, for fb and tweets, you have to constanly check the app for new notifications?

Another thing, from what i understand, the fb notifications are being pulled into the phone through specific time intervals instead of being pushed right?
