Radio only available online - disconnected multiple times

[tgagnebin]

I'm a recent premium subscriber and I'm a little disappointed that this is my best option for asking for help.  You guys need a dedicated customer support email address.

I'm often being disconnected from the spotify radio servers and then told I'm "offline" whereas I can listen to pandora and surf the web still....  happens A LOT.

Another very annoying issue is "this radio station is currently unavailable"... but I can listen to others.  Also happens A LOT.

Third issue is when I stop listening and come back to Spotify after a while, most of the time I cannot get the same radio station to start playing again, I have to pick a different one.

Pretty upset with the amount of issues I'm having and won't be paying any more money if it doesn't change real quick.  Open to suggestions on how to fix this.

I'm using an iPhone4S on AT&T.
