How do you sign off of the apps store?
I have an ipod touch with version 2.0, so I have the app store. I download a lot the free apps, so I have to sign in. But how do you sign off in the app store on the ipod touch? I have my family that goes through my touch including younger brothers and I don't want them buying useless apps. Also when I buy an app, are the new updates free? Like I want Ambiance app, but it says the new version will have more ambiance sounds, and I want them too. Do I have to wait for them or can I update for free? And are the extra download songs on tap tap revenge free? Thanks
