If I do a Factory reset will I loose all my accounts sign in info like foursquare,maps, the market or will it just automatically save my info and I will be able to login as usual once it resets.
What about google maps I will loose my starred places, and info stored as far as friends ect...I wont be able to just sign in and my info and friends,starred places will be there.
Before you do a reset you should make sure things like friends' addresses are saved to the corresponding contacts entry and make sure that gets backed up to Google's servers. As for starred places like restaurants you may like, those should automatically back up to Google's servers as well. If you sign in on the Google website and go to Maps you should see a list of your starred places.
