I noticed Pandora is available for the Curve 8320, but not for users with T-Mobile. Is there any way to get this app for a T-Mobile 8320? Slacker Radio is WAAAAAAAAY too slow.
Edit: Never mind. I just found a topic on it. Sorry.
The Pandoa mobile site now says it supports the 8320 on T-Mo. Originally, the list of supported carriers was pretty limited, but it looks like they've expanded it to the major US carriers. I got it about a week ago for my 8330 (before Sprint was listed as a supported carrier) and it works great!
