Selling my iphone 4s how do I save all info?

I'm selling my 4s and want to save all the information possible including contacts, pictures, notes (maybe even highscores). What is the best way to save it? I have a macbook pro if that helps.

Do a full sync to itunes it will save everything

If your connected to the cloud go to setting > icloud then scroll down and click back up. It will back up everything that you have checked. If you want to keep your apps connect it to your pc and and from there you can back up all your apps.

  • Which is more accurate regarding the details of an iphone, iphoneimei.info or imei.info? When I look up the IMEI of my broken iphone 5s on iphoneimei.info it says it's 16gb and when I look it up on imei.info it says it's 32gb… Which site is more accurate? The iphone is stuck in recovery mode and will not power on unless connected and it won't tell me the storage capacity in itunes.
  • Which is better: selling on amazon or selling on ebay? I have an individual seller account and I've noticed that my products sell much faster or ebay. However, I sold two iphones. My final sale fee $1100. However, ebay charged me a final sale fee of $135 Then I was charged $40 by paypal Then I paid $60 total to ship both items. On my amazon account I sold 1 phone. The phone cost $180 Amazon took out $30 Shipping cost $10 So I made $140
  • When changing sim cards, is all my info safe on my iphone? My old phone network is closing down so I'm changing to a new one. My new sim card will be activated in less than 3 hours. I've synced my iphone to itunes. Do I need to worry about losing all my contacts and notes and everything, or is it all stored safely on the phone?
  • Iphone stolen, can they see all my info? I got my iphone stolen from me last friday. I got my friend to try and track it but the app says the phone is dead. Wouldn't of someone turned it on by now? Why hasn't the app told my friend that its been turned on? Could the person have taken the sim card out and now i can't track it? I told my phone company to suspend it, so no one can use it. Its also locked. Can the person that stole it still be able to get a my info?
