I've only downloaded one song directly from my iPhone (pre 2.0 software w/App Store). It was pretty simple, and I had no issues. But just recently, I thought of a song I wanted to download, so I pulled out my phone, and clicked on the iTunes Store app, which began to open. But as it was opening, it went to the App Store. I tried looking for songs, but it only searched apps. Is something wrong? Does everyone have this issue?
