The apps are tied to an iTunes account, not the handset. So when syncing with another iTunes on another computer that is logged into an account that is different than the one the phone is using, the apps should be deleted. This will most likely happen if a) you change the iTunes account on the handset (which the new owner will have to do as otherwise it will be using the previous owners iTunes account - which the previous owner should deactivate otherwise it could get VERY expensive for them) and b) if you have "sync apps" checked in your iTunes.


Can't be a settings problem. Not sure exactly what you mean by "uploads in seconds but does not stop trying to upload". I'm guessing you mean it does upload the picture, but gets stuck on the uploading screen. Have you checked it's definitely uploading the image by checking on a computer that your image uploaded? Normally when the facebook app starts to play up, the easiest thing to do is delete the app off the phone and then download it again from the App Store.
