Having Trouble with Pandora

Phone: SE Xperia X10a (AT&T)
F/W: v1.6
Network: 3G

Hi guys I downloaded the Pandora app and I been listening to it today and I been bookmarking a lot of songs. All of them said they showed up successfully and when I tried going to My Profile at Pandora.com, the bookmarks would not show up. It says I don't have any. Does anyone know why this is? Thanks!
