Icon / zoom/ profile / giant icon pics

Great app! So thrilled to find this – solved a problem for me. I have a couple of questions:
1) On the iphone, when asked if I want to add home page, the icon that shows is white / blank. Can I add my logo?

2) On droid razor maxx, didn’t get asked if want to add to home page, is there a way to give users an icon?

3) Droid allowed the user to zoom the screen for easier reading. Is there something I can do to allow that for Iphone?

4) I created a home page and menu – worked great. I can’t figure out how to get the profile menu item to actually go to the profile. It takes the user to their activity feed. Is that correct?

5)Sitewide forums has really large icon pictures covering most of the screen. Is there something I should do to reduce those.
