Restoring

[Macgic]

i get this message in itunes saying an iphone has been previously synced etc. i am about to sell my phone and was wondering if when i do sell it will the new person see this? how do i hide my previous info? also do i just take my sim out when selling it? will the sim work in my old razor?

This is the current best method to wipe your iPhone.

It's saying that because iTunes keeps all of your iPhone settings. The new user wont have your settings in their iTunes. And when they plug it into their computer it will say the phone is linked to another computer and will need to be erased to use with theirs.
