My iTunes at work wants to update my iPhone to 2.0, which I already did at home. If I do it, it will erase all of my music, so I'm not going to do it. I visited the app store for the first time, downloaded a few, and sync'd (still at work), but they don't show up on my iPhone. WTF?! Do I need 2.0 to install these apps on my iPhone? Wait, I already upgraded to 2.0 weeks ago.
