Ok well should I change the permissions or just leave them since everything is fine.
That's up to you, if it's working fine I would leave well enough alone. Just remember for in the future, some applications must be set to "Allow" to function correctly, some do not. Also, don't download a bunch of apps at once, do it one at a time. That way you can pinpoint what application is causing the problem, like "everything was fine before I installed UberTwitter" if you download a bunch of apps at once, you'll have no idea which one it is and will have to delete one by one to figure it out...
