Do ipod touches have internet security?
Not really, but it doesn't really need any because it is so locked down. The only way to install software without jailbreaking is the app store. Apple have put a few pieces of protective software on it, but it doesn't really need any security software.
Is there a way to connect my Ipod touch to my dads iPhone 3g so i can get the internet on the ipod touch?
No ipod touches are not for buisness men they are more for kids because a buisness man would probably have a cell phone and plus you cant get the interternet everywhere only in certan places but on a cell phone you can get the internet any where.Ipod touches are probably most popular for its games and fun apps.
