1- keep wifi on... ? I'm not 100% sure but I think it'd work that way.

2- Internet sharing is tethering. There are some steps you have to take to get it to work though, just do a quick search here & you'll find it.

3- Most likely for traveling overseas where plugs are different. Slide out the US plug, slide in X country's plug.

4- This I do not know. Sorry.

5- Are you talking about Touch Flo or the start menu?

6- Again, not sure about this one. Sorry.
