Sadly there is no way to get your friends back. It is completely useless to call or mail Xbox on this concern. They keep no records of deleted or preferred friends. All you can do is try and remember people on your friends list, look at their friends list and hope that they added your previous friends
No they do not get deleted.
If you have already deleted it. im afraid you cant get it back, unless you have an xbox and live. You can get it back then
Xbox live Silver is for XBOX Live MarketPlace not for playing LIVE with you're friends that's what is the XBOX LIVE GOLD is.
Yes, an Xbox Live card has a back.
if you are asking is a non xbox live diffrent from a xbox live acount its not alike a non xbox live cant have other friends chat with you and play with you an xbox live account can play with people and chat with them on a headset or if one of your friends has a konnect you can video chat
The only way you can be in multiplayer you have to get xbox live account then you have to get xbox gold for it (-you have to buy it) after you get xbox live you can add your friends but they have to have xbox live and xbox gold to play with you.
